c语言程序编写（初学）（1） 编写一个简单计算器程序，输入格式为：data1 op data2.其中data1和data

#include
main()
{
char op;
float result,data1,data2;
float OP(float x,float y,char t);
printf("input op(+,-,*,/):n",op);
scanf("%c",&op);
printf("input data1:n",data1);
scanf("%f",&data1);
printf("input data2:n",data2);
scanf("%f",&data2);
result=OP(data1,data2,op);
printf("result=%f",result);
}
float OP(float x,float y,char t)
{
if(t=='+')
return x+y;
if(t=='-')
return x-y;
if(t=='*')

return x*y;
if(t=='/')
return x/y;
}
