printf("
%d",x);
}

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

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

#include 
#define x 5+2 
int main(){     
int i;     
i=x*x*x;     
printf("%d",i);      
return 0;  
} 

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

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

void main()
{
int z, a = 5, b = 3; z = a * 2 + 26 % 3;
printf("%d", z); }

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

main() 
{
int a = 0; 
for (; i = 0; i++) 
printf("%d", a); 
}

#include 
int main()
{     
float a=5.2;   
if(a==5.2)       
printf("Equal");    
else if(a<5.2)       
printf("Less than");    
else 
printf("Greater than");  
return 0;
} 

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