C Programming

Single correct

• AA static variable declared inside a function
• BAn array of integers declared inside a function
• CA dynamically allocated array of integers created using malloc() function call
• DReturn address of a function

#include <stdio.h>
int a=5;
int main(){
  int a=7;
  return(0);
}

#include <stdio.h>
int main(){
  int a=5;
  int a=7;
  return(0);
}

#include <stdio.h>
int main(){
  int a=5;
  float a=7;
  return(0);
}

Single correct

• AOnly P1 will compile without any error
• BOnly P2 will compile without any error
• COnly P3 will compile without any error
• DAll three programs P1, P2, and P3 will compile without any error

#include <stdio.h>
int main(){
  int *ptr, a, b, c;
  a=5; b=11; c=20;
  ptr=&a; *ptr=c; ptr=&c;
  a=*(&b); c=*ptr-a;
  printf("%d",c);
  return(0);
}
