Question

int main() {

while (1) {
float d;
scanf("%f", &d);
float x;
for (x = d; x <= d + 1000.0; x = x + 1000.0) {
}
printf("loop exited with x = %.14g\n", x);
}
return 0;
}

If you run the program, you will see. What number should I use as an input to make this an infinite loop?

Answer 1

Answer:

We will use a string or character instead of float or integer. Since d is declared as float and when we will give a string or character as a input and it will make an error in the program that will take the for loop in the program into infinte loop.
