Discussion Forum : Control Instructions - Find Output of Program (Q.No. 2)
2.
What will be the output of the program?
#include<stdio.h>
int main()
{
char str[]="C-program";
int a = 5;
printf(a >10?"Ps\n":"%s\n", str);
return 0;
}
Answer: Option
Explanation:
Step 1: char str[]="C-program"; here variable str contains "C-program".
Step 2: int a = 5; here variable a contains "5".
Step 3: printf(a >10?"Ps\n":"%s\n", str); this statement can be written as
if(a > 10)
{
printf("Ps\n");
}
else
{
printf("%s\n", str);
}
Here we are checking a > 10 means 5 > 10. Hence this condition will be failed. So it prints variable str.
Hence the output is "C-program".

@Saikrishna.
Here is the use of conditionl operator .The syntax for conditional operator is :
var=(condition)?statement1:statement2;
If the condition will be true then the 1st statement is executed and for false statement2.
so, here condition false so the 2nd statement will be that means pintf("%s",str); will be remaining for str print c-programming.
That's all thanks.

Conditonal statement is used in printf func nothing logic is used.

Sorry but I did not get any of above explanation because as there is no value assigned to ps how it comes to role here.

This is an ternary or conditional operator that's why it execute exp2 in this operator.
If the given condition is true exp1 will execute else exp 2 will execute here the condition is (a>10) but the value of a is 5.
So the given condition is false that's the answer will be printed as c-language.

@Rani.
We get ps as a output only when the condition a>10 is satisfies but acc to the given data the condition is failed so pn is not an output.

"ps" is nothing but it will print if the condition (a>10).

What about "Ps"?

Printf statenment contains one if condition with true block and else block a>10 means if (a>10) the condition is false so the else statement will execute print the str value is c_program.
