1.不多说上代码
#include<stdio.h>typedef enum{female,male}Sextype;typedef struct{Sextype sextype;int Number;}School;typedef struct{int MaleSum;int FemaleSum;int AllSum;}Num;Num Sumscore(School* sn, int n);int main(){Sn shool[3] = {{female,10},{male,15},{female,20} };Num num;num = Sumscore(shool,3);printf("male=%d,female=%d,all=%d\n", num.MaleSum,num.FemaleSum,num.AllSum);return 0;}Num Sumscore(School* sn,int n){Num temp = {0,0,0};for (int i = 0; i < n; i++){if (sn[i].sextype == female)temp.FemaleSum += sn[i].Number;elsetemp.MaleSum += sn[i].Number;temp.AllSum += sn[i].Number;}return temp;}
如果初学者对typedef这个函数的使用不熟悉的话，下面这串代码去掉typedef
#include<stdio.h>enum Sextype{female,male};struct School{enum Sextype sextype;int Number;};struct Number{int MaleSum;int FemaleSum;int AllSum;};struct Number Sumscore(struct School* sn, int n);int main(){struct School school[3] = {{female,10},{male,15},{female,20} };struct Number num;num = Sumscore(school,3);printf("male=%d,female=%d,all=%d\n", num.MaleSum,num.FemaleSum,num.AllSum);return 0;}struct Number Sumscore(struct School* school,int n){struct Number temp = {0,0,0};for (int i = 0; i < n; i++){if (school[i].sextype == female)temp.FemaleSum += school[i].Number;elsetemp.MaleSum += school[i].Number;temp.AllSum += school[i].Number;}return temp;}
结果运行效果截图：
运行没问题，这里解释一下如何把结构体数组作为参数传入函数，其实在C语言中，任何数组都可以用首地址加上数组长度的方式传入函数，结构体数组也是数组，同样可以以首地址加上数组长度的方式传入函数，需要注意是仅仅只有别把传入的数据类型给搞错了。（我想学到结构体这个地方了，指针应该比较熟悉了吧，如果不理解为什么首地址加上长度可以表示数组的原因，可以搜索数组传入函数这个问题）
