请各位大侠帮帮忙~为什么此程序无法执行~

看看你的GetReal函数有没有问题。printf("The total is %g\n",total); －－》printf("The total is %f\n",total);

#include<stdio.h>

void main()
{
float n1,n2,total;

printf("This program adds two floating-point numbers.\n");

printf("1st number?\n");
scanf("%f",&n1);
//n1=GetReal();

printf("2nd number?\n");
scanf("%f",&n2);
//n2=GetReal();

total=n1+n2;
printf("The total is %f\n",total);
}

在#include<stdio.h>后增加:
double GetReal()
{
double f;
scanf("%lf",&f);
return f;
}
