本题要求实现一个计算输入的两数的和与差的简单函数。
函数接口定义：
void sum_diff( float op1, float op2, float *psum, float *pdiff );
其中op1和op2是输入的两个实数，psum和pdiff是计算得出的和与差
#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;
}
void sum_diff( float op1, float op2, float *psum, float *pdiff )
{
*psum = op1 + op2 ;
*pdiff = op1 - op2 ;
}
