1.What will be the output of following program ?

Note : int-4bytes

#include

int main()

{

    struct sample{

        int a;

        int b;

        sample *s;

    }t;

 

    printf("%d,%d",sizeof(sample),sizeof(t.s));

    return 0;

}

 

2.What will be the output of following program ?

#include

int main()

{

struct std

{

char name[30];

int age;

};

struct std s1={"Mike",26};

struct std s2=s1;

printf("Name: %s, Age: %d\n",s2.name,s2.age);

}

3.What will be the output of following program ?

#include

#include

int main()

{

    char str1[]="IncludeHelp",str2[]=".Com";

    printf("%s",str1+strlen(str2));

    return 0;

}

4)Predict the output:

#include

int main()

{

    char str[]="Hello%s%dFriends";

    printf(str);

    printf("\n");

    printf("%s",str);

    return 0;

}

5)Predict the output

#include

#include

int main()

{

    char s1[]="IncludeHelp";

    char s2[10];

     

    strncpy(s2,s1,5);

    printf("%s",s2);

    return 0;

}

6) Predict the output

#include

int main()

{

    char *str="IncludeHelp";

    while(*str)

        printf("%s\n",str++);

    return 0;

}

7. ) Predict the output

#include

int main()

{

    int a=10,b=2;

    int *pa=&a,*pb=&b;

    printf("value = %d", *pa/*pb);

    return 0;

}

8. Predict the output

#include

#define TEXT IncludeHelp

int main()

{

    printf("%s",TEXT);

    return 0;

}

9. Predict the output

#include

#define MAX 99

int main()

{

    printf("%d...",MAX);

#undef MAX

    printf("%d",MAX);

    return 0;

}

10. Predict the output

#include

int main(){

    char val=250;

    int  ans;

    ans= val+ !val + ~val + ++val;

    printf("%d",ans);

    return 0;

}

11. Predict the output

#include

int main()

{

    int x,y;

    x=(100,200);

    y=100,200;

    printf("x=%d,y=%d",x,y);

  return 0;

}

12. Predict the output

#include < stdio.h >

void main()

{   unsigned char var=0;

    for(var=0;var<=255;var++)

    {

        printf("%d ",var);

    }

}

13. Predict the output

#include

#define TRUE 1

int main()

{

    int loop=10;

    while(printf("Hello ") && loop--);

}

14. Predict the output

#include

void main()

{

int k = 8;

int x = 0 == 1 && k++;

printf("%d %d\n", x, k);

}

15. Predict the output

#include

main()

{

int x=4;

printf("%d",printf(" %d %d ",x,x) );

}
