Discussion Forum : Expressions - Find Output of Program (Q.No. 13)
13.
What will be the output of the program?
#include<stdio.h>
int main()
{
int k, num=30;
k = (num>5 ? (num <=10 ? 100 : 200): 500);
printf("%d\n", num);
return 0;
}
Answer: Option
Explanation:
Step 1: int k, num=30; here variable k and num are declared as an integer type and variable num is initialized to '30'.
Step 2: k = (num>5 ? (num <=10 ? 100 : 200): 500); This statement does not affect the output of the program. Because we are going to print the variable num in the next statement. So, we skip this statement.
Step 3: printf("%d\n", num); It prints the value of variable num '30'
Step 3: Hence the output of the program is '30'

Could you explain what o/p will be the result of
int x=3, y=4, z=4;
printf("ans=%d",(z>=y>=x?100:200));
int x=3, y=4, z=4;
printf("ans=%d",(z>=y>=x?100:200));

Its independent to Ternary operator because software expression are differ with this.

Dear Sir,
According to your problem resolve, It could not be:
k = (num>5 ? (num <=10 ? 100:200):500).
Given.
k = (num>5 ? (num <=10 ? 100:200):500);
Answer : 30.
Actual answer : 30 (but expression error available).

#include <stdio.h>
int main() {
int a=400,b=700;
if(!a<=500)
{
b=80;
c=90;
printf("%d %d",b,c);
}
return 0;
}
How does the condition works with a works? Can u please help me?

Explain if we print k value what will happen in the k = (num>5 ? (num <=10 ? 100 : 200): 500);

Ternary operators work like this:
int a,b,c;
a = (condition) ? value if true : value if false;
In this example there is a nested ternary operation, but the question was tricky.

Will above statement show error message or not?

i=4;
printf("i=%d,%d,%d,%d",i,++i,i++,--i);
the answer in fedora(linux platform) is 5,5,3,5...hw is it??

@Thirupathi.
Skip this statement k = (num>5 ? (num <=10 ? 100 : 200) : 500) ;
Because we have to print the value of num not the value of k.
So it will print num=30.
Thanks.
