Test: Basics of Structures - Class 6 MCQ

since this program isn't having any syntax error so program is executed. It is clearly seen that 99 is not divisible by 5. So if statement will not execute and program will terminate.

When we give scanf() a "%f" format string, that means "We want you to try and get us a floating point number. When we provide input like 'xyz', it's not going to match anything, because 'xyz' is not a valid floating-point number.

comma operator is executed from left to right so until j<20 for loop statement is true, so both i and j are incremented.
So, i = 20 and j = 20.

Here if condition evaluates to true as a non-zero value i.e 5 is assigned to a.
So the value of a = 5 and after increment value of b = 6.
In printf statement due to pre-increment of a value of a printed will be 6 and due to post-increment of b value of b printed will be 6 and not 7.

Expression value2%5 is equal to 0 and this value assigned to value1.
Therefore if condition reduces to if(0) so it fails.
Therefore body of if will not be executed i.e num = 5 will not be assigned.
So at printf num = 100 , value1 = 0 and value2 = 100.

the if is conditional and it checks for expression whether it is zero or non-zero so it doesn't print any data it is clear and it is clearly seen that there is not a single syntax error therefore no complier error.
After compling the program will be executed but there is not a single printf statement so it is executed but will not give any output.

Here if statement is executed since we know that printf() function return the number of character print.
Here printf("%d", i) return 2 because it print 1 and newline i.e 2.
And, printf("%d', j) return 3 because it print -1 and newline i.e number of character is 3.
Therefore if statement look like if(2<3) yes its true.
So if statement will execute. And answer is 1 -1 1.

Condition if(c[a]%2 == 1) forces only odd numbers to add in the sum.

Here if Statement is true and if statement executes left to right. Since its AND operator so all the condition should be check until it finds any false statement. Initially y = 10 In 1st condition: y++>9 which is true and y become 11 in next use. In 2nd condition: y++!=10 which is also true and y become 12 in next use In 3rd condition: y++>11 which is also true and y become 13 in next use After that printf statement will execute and print y = 13

First of all for loop have no braces so for loop on have only next line in its body.
for( ; digit <= 9; )
digit++;
After completing for loop digit = 10;
next statement digit *= 2; i.e digit = digit * 2 = 20;
next statement digit--; i.e 20-- => 19
So final value of digit is 19
