How does this program work?

Question

#include 

int main() {
    float a = 1234.5f;
    printf(\"%d\\n\", a);
    return 0;
}

It displays a 0!! How is that

Answer 1

It won't convert automatically float to integer. Because both has different format of storage. So if you want to convert, use (int) typecasting.

#include 

int main() {
    float a = 1234.5f;
    printf("%d\n", (int)a);
    return 0;
}
