4. int y = 10000;

5. int y = 34;

6. printf("Hello World! %d\n", y);

7. return 0;

8. }

• Compile time error

• 10000
• Hello World!
• int y = 50;

for(x = 1; x = 3; x++)

How many times above loop would run?

• 4

• Never

• 3

• 5

#include<stdio.h>

void main() {
int num = 0;
do {
- - num;
printf(“%d”, num);
num ++;
}
while(num >= 0);
}

• A run time error will be reported

• The program will not enter into the loop

• The loop will run infinitely many times

• Compile time error

#include <stdio.h>

int main() {
