以混合数字格式制作分数输出

Question

我制作了一个程序，所以当用户选择选项1时，他们可以输入分子然后输入分母，如果他们选择选项2，它将打印该分数。但是我希望它以混合形式打印分数。例如，如果我做了20/3，它将打印为6 2/3。关于我如何解决这个问题的任何帮助？

这是我的代码（希望很容易阅读（：）

#include <stdio.h>
#include <stdlib.h>

//Struct to hold fraction data
typedef struct fraction
{
int numerator, denom;
}fraction;


int main()
{
//Array of 100 fractions
fraction arrFraction[100];

int i = 0, j, num = 1;

//Loop till user want to stop

while (num == 1)
{
    int choice;
    printf("\nPress 1 to enter a fraction\n");
    printf("Press 2 to view stored fractions\n");
    scanf("%d", &choice);


    if(choice == 1)
    {
        //Prompting user
        printf("\nEnter your fraction, numerator followed by denominator\n    ");

        //Reading values from user
        scanf("%d %d", &arrFraction[i].numerator, &arrFraction[i].denom);

        //Incrementing counter
        i++;

    }

    if (choice == 2) {

        for (j = 0; j < i; j++)
        {
            //Printing fractions
            printf("\n  %d / %d \n",  arrFraction[j].numerator,     arrFraction[j].denom);
        }

    }
}//end of while loop



return(0);
}

Answer 1

您可以使用除法（/）和模数（％）运算符。

    printf("%d %d/%d",  
      arrFraction[j].numerator / arrFraction[j].denom , 
      arrFraction[j].numerator / arrFraction[j].denom , 
      arrFraction[j].denom
    );
