How do we check if a file has reached its end?

What is the output of the following code?

main()

{

char *p="Caritor";

*++p;

printf("%c",*p);

*++p;

printf("%c",*p);

}

The file “iostream” includes

Which of the following is the correct syntax for including a user-defined header file in C++?

Which one of the following options is correct?

Consider the following program:

int f(int *p, int n) {     if (n <= 1) return 0;     else return max(f(p+1,n-1),p[0]-p[1]); } int main() {     int a[] = {3,5,2,6,4};     printf("%d", f(a,5)); }

Note: max(x,y) returns the maximum of x and y. The value printed by this program is

What is the output of the following C program?

int main()

{

   struct school

   {

      int rank;

      struct class

      {

        int strength;

      }class1;

   }school1;

   school1.rank = 1;

   school1.class1.strength = 60;

   printf("%d %d", school1.rank, school1.class1.strength);

}

Consider the following C program:

# include <stdio.h> int main( ) {    int i, j, k = 0;    j = 2 * 3 / 4 + 2.0 / 5 + 8 / 5;    k  -= --j;    for (i = 0; i < 5; i++)    {       switch(i + k)       {          case 1:          case 2: printf("n%d", i + k);          case 3: printf("n%d", i + k);          default: printf("n%d", i + k);       }    }    return 0; }

The number of times printf statement is executed is __________.

Consider the following C program.

#include <stdio.h> #include <string.h> void printlength (char *s, char *t) { unsigned int c = 0; int len = ((strlen (s) - strlen (t)) > c) ? strlen (s) : strlen (t); printf("%dn", len); } void main() { char *x = "abc"; char *y = "defgh"; printlength(x, y); }

Recall that strlen is defined in string.h as returning a value of type size_t, which is an unsigned int . The output of the program is

What is the output of the following code?

#include<stdio.h>

int main()

{

  static int arr[]={0,1,2,3,4};

  int *p[]={arr,arr+1,arr+2,arr+3,arr+4};

  int **ptr=p;

  ptr++;

  printf("\n %d %d %d",ptr-p, *ptr-arr, **ptr);

  *ptr++;

  printf("\n %d %d %d",ptr-p, *ptr-arr, **ptr);

  *++ptr;

  printf("\n %d %d %d",ptr-p, *ptr-arr, **ptr);

  ++*ptr;

  printf("\n %d %d %d",ptr-p, *ptr-arr, **ptr);

  return 0;

}
