C Loops - 1 Free MCQ Practice Test with Solutions

Test: C Loops - 1 - Question 1

What is the output of C Program.?
int main()
{
int a=14;

while(a<20)
{
++a;
if(a>=16 && a<=18)
{
continue;
}
printf("%d ", a);

}
return 0;
}

A.
15 16 17 18 19
B.
15 18 19
C.
15 16 20
D.
15 19 20

Detailed Solution: Question 1

Between 16 - 18, continue statement skips all other statements below it. So a will not be printed during that time.
15 printed
16 not printed
17 not printed
18 not printed
19 printed
20 printed

Test: C Loops - 1 - Question 2

Choose a correct statement about C language break; statement.

A.
A single break; statement can force execution control to come out of only one loop.
B.
A single break; statement can force execution control to come out of a maximum of two nested loops.
C.
A single break; statement can force execution control to come out of a maximum of three nested loops.
D.
None of the above.

Detailed Solution: Question 2

The correct statement is:

1. A single break; statement can force execution control to come out of only one loop.

Explanation:

In C language, a break; statement is used to exit the nearest enclosing loop (or switch statement) in which it is placed. It does not affect any outer loops if there are nested loops. Therefore, a single break; statement only forces the control to exit the innermost loop.

Test: C Loops - 1 - Question 3

What is the output of C Program.?
int main()
{
int a=10, b, c;
b=a++;
c=++a;
printf("%d %d %d", a, b, c);
return 0;
}

A.
10 11 12
B.
12 10 12
C.
12 11 12
D.
12 12 12

Detailed Solution: Question 3

a++ first assigns 10 to b. Next a is incremented separately. ++a increments from 11 to 12. Final ++a value is assigned to the left side variable C.

Test: C Loops - 1 - Question 4

What is the output of C Program.?
int main()
{
int a=10,b=20;

if(a==9 AND b==20)
{
printf("Hurray..");
}

if(a==10 OR b==21)
{
printf("Theatre");
}
return 0;
}

A.
Theatre
B.
Hurray
Theatre
C.
No output
D.
Compiler error

Detailed Solution: Question 4

There are no keywords like AND / OR in C language. Logical OR is represented with two Pipes ||. Logical AND is represented with two Ampersands &&.

Test: C Loops - 1 - Question 5

Expand or Abbreviate ASCII with regard to C Language.

A.
Australian Standard Code for Information Interchange
B.
American Standard Code for Information Interchange
C.
American Symbolic Code for Information Interchange
D.
Australian Symbolic Code for Information Interchange

Detailed Solution: Question 5

There were only 128 Characters with 7 Bits in Original ASCII specification. Present character standard in all modern programming languages is UNICODE which covers all languages, Emojis and other special symbols all over the world.

Test: C Loops - 1 - Question 6

Choose facts about continue; statement is C Language.

A.
continue; is used to take the execution control to next iteration or sequence
B.
continue; statement causes the statements below it to skip for execution
C.
continue; is usually accompanied by IF statement.
D.
All the above.

Detailed Solution: Question 6

A: continue; is used to take the execution control to next iteration or sequence

This is true. The continue; statement in C is used to skip the current iteration of a loop and move to the next iteration of the loop. For example, in a for, while, or do-while loop, when continue; is executed, it stops executing the remaining statements in the current iteration and moves to the next iteration.

B: continue; statement causes the statements below it to skip for execution

This is also true. When the continue; statement is encountered, the code after it in the current iteration of the loop is skipped, and the control jumps to the next iteration of the loop. For example, in a for loop, the increment or update part will be executed, and the loop will continue to the next iteration.

C: continue; is usually accompanied by if statement

This is generally true. The continue; statement is often used inside conditional statements (like if) to determine when to skip to the next iteration. For example:

for (int i = 0; i < 10; i++) {

if (i == 5) {

continue; // Skip the rest of the loop body when i is 5

}

printf("%d ", i);

}

In this example, the continue; is used with an if condition to skip the print statement when i is 5.

Thus, all the statements A, B, and C are correct, so the answer is D: All the above.

Test: C Loops - 1 - Question 7

Choose a correct statement about C break; statement.?

A.
break; statement can be used inside switch block
B.
break; statement can be used with loops like for, while and do while.
C.
break; statement causes only the same or inner loop where break; is present to quit suddenly.
D.
All the above.

Detailed Solution: Question 7

C break; statement is a key feature in the C programming language, and it has specific uses within code structures. Here’s a concise overview of its applications:

The break; statement can be used within a switch block to exit the block after a case has been executed.
It is also applicable in loops such as for, while, and do while, allowing you to terminate the loop prematurely.
When invoked, the break; statement causes the current loop to exit immediately, affecting only the loop in which it is called. This means any outer loops remain unaffected.

In summary, the break; statement serves multiple functions in controlling the flow of a program by allowing exits from both loops and switch cases.

Test: C Loops - 1 - Question 8

Choose a correct C Statement regarding for loop.
for(; ;);

A.
for loop works exactly first time
B.
for loop works infinite number of times
C.
Compiler error
D.
None of the above

Detailed Solution: Question 8

We are not specifying condition to exit the loop. Eg. for(a=0;a<10;a++)

Test: C Loops - 1 - Question 9

What is the output of C Program.?
int main()
{
int a=0, b=0;
while(++a < 4)
printf("%d ", a);
while(b++ < 4)
printf("%d ", b);
return 0;
}

A.
0 1 2 3 1 2 3 4
B.
1 2 3 1 2 3 4
C.
1 2 3 4 1 2 3 4
D.
1 2 3 4 0 1 2 3

Detailed Solution: Question 9

(++a < 4) first increments and compares afterwards. (b++ < 4) first compares and increments afterwards.

Test: C Loops - 1 - Question 10

What are C ASCII character ranges.?

A.
A to Z = 65 to 91
B.
a to z = 97 to 122
C.
0 to 9 = 48 to 57
D.
All the above

Detailed Solution: Question 10

All remaining characters are special characters or symbols in C Language. 0 to 47, 58 to 64, 91 to 96, 123 to 127.
