1000+ C Programming MCQ for JEE Main [Solved]

void main() 
{
int a = 0; 
while (a<=50) for(;;) if(++a % 50==0) break;
printf("a = %d", a); 
}

int x=40;
main(){
int x=20;
printf("
%d",x);
}

main() 
{ 
int sub[50]; 
for(i=0; i<=48;i++) 
{ 
sub[i]=i; 
printf("
%d", sub[i]);
}
}

main() 
{
int a = 5, b = 6; 
(a == b? printf("%d", a)); 
}

void main() 
{
float a;
int x = 10, y = 3; a = x / y;
printf("%f", a); }

What will be output if you will compile and execute the following c code?

#include 
int main(){     
char c=125;     
c=c+10;     
printf("%d",c);     
return 0;   
} 

main() 
{ 
xyz: goto abc;
printf("Hello"); 
abc: printf("World");
goto xyz;
}

main() 
{ 
int k, num = 30; 
k = (num > 5 ? (num <= 10 ? 100 : 200) : 500); 
printf("
%d", num); 
}

void change (char *k) 
{
k="Hello";
return; 
} 
main() 
{ 
char *ch = "World";;
change(ch); 
printf("%s", ch); 
}

#define sqr(x= x*x) 
main() 
{
int a = 10, b = 5; 
printf("%d, %d", sqr(a+b),sqr(++a));
}

void main() 
{
int a = 1, b=2; 
int *ip; 
ip=&a; 
b=*ip; 
printf("%d", b);
}

void main() 
{
char a = 'B';
switch (a) 
{
case 'A' : printf("a"); 
case 'B' : printf("b");
default : printf("c");
}
