- What will be the output of the following nested if-else statement?
#include<stdio.h>
void main(){
int x=0;
If(x++){
printf("TRUE");
}
else if(x == 1){
printf("FALSE");
}
}
ANS: Compile time error
EXPLANATION: In line-4 'if' is a keyword which is always in lower cases.
- Select the correct output for the below C code?
#include <stdio.h>
static int i = 10;
int main() {
i = 5;
for(i = 0; i < 5; i++) {
static int a = 10;
printf("%d ", a++);
}
return 0;
}
ANS: 10 11 12 13 14
EXPLANATION: A static int variable remains in memory while the program is running.
In first iteration,
i=0, 0<5 condition is true inside the loop variable a is declared as static int and initialized with value 10. Now print value of a(10) and then increment a value(11).
In second iteration,
i=1, 1<5 condition true, a never initialized again because of static, print value of a(11) and then increment a value(12),...,so on.
- What is the output of the code given below?
#include<stdio.h>
void main() {
int i = 0;
do {
i++ = ++i;
printf("Hello CodeMarathon");
} while (i < 0);
}
ANS: Compile time error
EXPLANATION: We can not use increment left-side of assignment operator.
