To print out a and b given below, which of the following printf() statement will you use?float a=3.14:double b=3.14;

To print out the variables a and b, you would use the printf() function in C language with the appropriate format specifiers. Since a is a float and b is a double, the correct format specifiers would be %f for both.

Here’s how you can do it:

#include <stdio.h>

int main() {
    float a = 3.14f;  // Notice the 'f' suffix for float
    double b = 3.14;  // No suffix needed for double
    
    // Print the variables
    printf("a = %f\n", a);
    printf("b = %f\n", b);

    return 0;
}

In this code snippet:

1. We define a as a float and b as a double.
2. The printf() function is used to print each variable, using the %f format specifier for both.

In summary, to print a and b, use the following printf() statements:

printf("a = %f\n", a);
printf("b = %f\n", b);
