Exercise 8-2 calculate the sum and difference of two numbers

practice 8-2 Calculate the sum and difference of two numbers (10 branch )

This problem requires a simple function to calculate the sum and difference of two input numbers .

Function interface definition ：

void sum_diff( float op1, float op2, float *psum, float *pdiff );

among op1 and op2 Are two real numbers entered ,*psum and *pdiff Is the calculated sum and difference .

Sample referee test procedure ：

#include <stdio.h>

void sum_diff( float op1, float op2, float *psum, float *pdiff );

int main()
{
    float a, b, sum, diff;

    scanf("%f %f", &a, &b);
    sum_diff(a, b, &sum, &diff);
    printf("The sum is %.2f\nThe diff is %.2f\n", sum, diff);
    
    return 0; 
}

/*  Your code will be embedded here  */

sample input ：

4 6

sample output ：

The sum is 10.00
The diff is -2.00

void sum_diff( float op1, float op2, float *psum, float *pdiff ){
    *psum=op1+op2;
    *pdiff=op1-op2;
}
