INTERVIEW QUESTIONS C++ INPUT AND OUTPUT OPERATIONS IN C++ DETAILS

Question: What is the output of printf ("%d")

Answer: Usually the output value cannot be predicted. It will not give any error. It will print a garbage value. But if the situation is

main()

{

int a=1,b=2,c=3;

printf("%d");

}

The output will be the value of the last variable, ie. 3

This will give garbage value. Source: CoolInterview.com

It prints garbage value. Source: CoolInterview.com

void main()
{
int a=1,b=2,c=3;
clrscr();
printf("%d");
}
output: 3
because convention of storing variables in c is from right to left i.e. c then b then a
hence when we print the value of c at the top of the stack and gets printed Source: CoolInterview.com

The last value stored in the stack will get printed to the console. Source: CoolInterview.com

int main()
{
printf("%d");
return 0;
}

This program print 0(zero). I have tried it in visual c++ and turbo c. Source: CoolInterview.com
