没错，初学者的简单计算机，计算整数加减乘除（整除的）。 #include <stdio.h> #include<Windows.h> #pragma warning(disable:4996) int MyAdd(int x, int y){ return x + y; } int MySub(int x, int y){ return x -y; } int MyMul(int x, int y){ return x * y; } int MyDiv(int x, int y){ return x / y; } int main() { while (1){ int x = 0; int y = 0; char op = ‘x’; printf(“请先输入两个数字再输入运算符号\n”); scanf("%d %d %c", &x, &y, &op); if (op == ‘+’){ printf("%d+%d=%d\n", x, y, MyAdd(x, y)); } else if (op == ‘-’){ printf("%d-%d=%d\n", x, y, MySub(x, y)); } else if (op == '’){ printf("%d%d=%d\n", x, y, MyMul(x, y)); } else if (op == ‘/’){ if (y == 0){ printf(“输入错误\n”); } else{ printf("%d/%d=%d\n", x, y, MyDiv(x, y)); } } else{ printf(“输入错误\n”); } system(“pause”);
}}
