What will be the output of the following C code?

    #include <stdio.h>
    int main()
    {
        int var = 010;
        printf("%d", var);
    }

Detailed Solution for Test: C Constants - Question 3

010 is octal representation of 8.
Output:

8

Test: C Constants - Question 4
Save

What will be the output of the following C code?

    #include <stdio.h>
    #define MAX 2
    enum bird {SPARROW = MAX + 1, PARROT = SPARROW + MAX};
    int main()
    {
        enum bird b = PARROT;
        printf("%d\n", b);
        return 0;
    }
Detailed Solution for Test: C Constants - Question 4

MAX value is 2 and hence PARROT will have value 3 + 2.
Output:
$ cc pgm6.c
$ a.out
5

Test: C Constants - Question 6
Save

What will be the output of the following C code?

    #include <stdio.h>
    int main()
    {
        printf("sanfoundry\r\nclass\n");
        return 0;
    }
Detailed Solution for Test: C Constants - Question 6

rn combination makes the cursor move to the next line.
Output:
$ cc pgm9.c
$ a.out
sanfoundry
class

Test: C Constants - Question 7
Save

What will be the output of the following C code?

    #include <stdio.h>
    void main()
    {
        int k = 4;
        int *const p = &k;
        int r = 3;
        p = &r;
        printf("%d", p);
    }
Detailed Solution for Test: C Constants - Question 7

Since the pointer p is declared to be constant, trying to assign it with a new value results in an error.
Output:
$ cc pgm11.c
pgm11.c: In function ‘main’:
pgm11.c:7: error: assignment of read-only variable ‘p’
pgm11.c:8: warning: format ‘%d’ expects type ‘int’, but argument 2 has type ‘int * const’

Test: C Constants - Question 8
Save

What will be the output of the following C code?

    #include <stdio.h>
    void main()
    {
        int const k = 5;
        k++;
        printf("k is %d", k);
    }
Detailed Solution for Test: C Constants - Question 8

Constant variable has to be declared and defined at the same time. Trying to change it results in an error.
Output:
$ cc pgm12.c
pgm12.c: In function ‘main’:
pgm12.c:5: error: increment of read-only variable ‘k’

Test: C Constants - Question 9
Save

What will be the output of the following C code?

    #include <stdio.h>
    int main()
    {
        printf("C programming %s", "Class by\n%s Sanfoundry", "WOW");
    }
Detailed Solution for Test: C Constants - Question 9

This program has only one %s within first double quotes, so it does not read the string “WOW”.
The %s along with the Sanfoundry is not read as a format modifier while new line character prints the new line.
Output:
$ cc pgm2.c
$ a.out
C programming Class by
%s Sanfoundry

Test: C Constants - Question 10
Save

What will be the output of the following C code?

    #include <stdio.h>
    #define a 10
    int main()
    {
        const int a = 5;
        printf("a = %d\n", a);
    }
Detailed Solution for Test: C Constants - Question 10

The #define substitutes a with 10 without leaving any identifier, which results in Compilation error.
Output:
$ cc pgm3.c
pgm3.c: In function ‘main’:
pgm3.c:5: error: expected identifier or ‘(’ before numeric constant

Test: C Constants - Question 11
Save

What will be the output of the following C function?

    #include <stdio.h>
    enum birds {SPARROW, PEACOCK, PARROT};
    enum animals {TIGER = 8, LION, RABBIT, ZEBRA};
    int main()
    {
        enum birds m = TIGER;
        int k;
        k = m;
        printf("%d\n", k);
        return 0;
    }
Detailed Solution for Test: C Constants - Question 11

m is an integer constant, hence it is compatible.
Output:
$ cc pgm5.c
$ a.out
8

Test: C Constants - Question 12
Save

What will be the output of the following C code?

    #include <stdio.h>
    #include <string.h>
    int main()
    {
        char *str = "x";
        char c = 'x';
        char ary[1];
        ary[0] = c;
        printf("%d %d", strlen(str), strlen(ary));
        return 0;
    }
Detailed Solution for Test: C Constants - Question 12

str is null terminated, but ary is not null terminated.
Output:
$ cc pgm7.c
$ a.out
1 5

    }
Detailed Solution for Test: C Constants - Question 14

Since the constant variable has to be declared and defined at the same time, not doing it results in an error.
Output:
$ cc pgm10.c
pgm10.c: In function ‘main’:
pgm10.c:5: error: assignment of read-only variable ‘p’
