# C 程序：查找商和余数 > 原文： [https://beginnersbook.com/2017/09/c-program-to-find-quotient-and-remainder/](https://beginnersbook.com/2017/09/c-program-to-find-quotient-and-remainder/) 程序根据用户输入的被除数和除数查找**商**和**余数**。 ## 示例 1：用于查找商和余数的程序 在该程序中，要求用户输入被除数和除数，然后程序根据输入值查找商和余数。 ```c #include <stdio.h> int main(){ int num1, num2, quot, rem; printf("Enter dividend: "); scanf("%d", &num1); printf("Enter divisor: "); scanf("%d", &num2); /* The "/" Arithmetic operator returns the quotient * Here the num1 is divided by num2 and the quotient * is assigned to the variable quot */ quot = num1 / num2; /* The modulus operator "%" returns the remainder after * dividing num1 by num2. */ rem = num1 % num2; printf("Quotient is: %d\n", quot); printf("Remainder is: %d", rem); return 0; } ``` 输出： ```c Enter dividend: 15 Enter divisor: 2 Quotient is: 7 Remainder is: 1 ``` ## 示例 2：使用函数查找商和余数的程序 在这个程序中，我们正在做上述程序的相同的事情，但是在这里我们使用函数来查找商和余数。我们为计算创建了两个用户定义的函数。要理解这个程序，您应该对以下 [C 编程](https://beginnersbook.com/2014/01/c-tutorial-for-beginners-with-examples/)主题有基本的了解： 1. [C 中的函数](https://beginnersbook.com/2014/01/c-functions-examples/) 2. [C 中的按值函数调用](https://beginnersbook.com/2014/01/c-function-call-by-value-example/) ```c #include <stdio.h> // Function to computer quotient int quotient(int a, int b){ return a / b; } // Function to computer remainder int remainder(int a, int b){ return a % b; } int main(){ int num1, num2, quot, rem; printf("Enter dividend: ");    scanf("%d", &num1); printf("Enter divisor: ");    scanf("%d", &num2); //Calling function quotient()    quot = quotient(num1, num2); //Calling function remainder()    rem = remainder(num1, num2); printf("Quotient is: %d\n", quot);    printf("Remainder is: %d", rem); return 0; } ``` 查看相关的 [C 程序](https://beginnersbook.com/2015/02/simple-c-programs/)： 1.
