How to use if-else statement in c programming

 In the program below, we will learn about how the if-else statement works. I wanted to calculate 4th power of a given number if and only if it is greater than 2, else if the value of given number lowers than and equal to 2, it always shows result by adding up with 3.

        /*To verify the if else statement */
        #include<stdio.h>
        #include<math.h>
        int main()
        {
            float a, b;
            printf("Enter the value of a:");
            scanf("%f", &a);
            if (a>2)
            b=pow(a,4);
            else b=a+3;
            printf("\n The calculated value is: %f\n", b);
            return(0);
        }
