cout<<a[i]<<endl;sort(a,a+10,greater<int>());for(inti=0;i<10;i++) cout<<a[i]<<endl;return0; } 那么sort能否在c中实现呢 回到顶部 c中自带的qsort函数 #include<stdio.h>#include<stdlib.h>intcmp(constvoid*a ,constvoid*b ){return*(

void是C语言中的一个关键字，其含义因其应用形式不同，一般分为两种：void和void void的字面意思是“无类型”，void *则为“无类型指针”，void *可以指向任何类型的数据。void几乎只有“注释”和限制程序的作用，定义一个void变量没有意义，不妨试着定义：这行语句编译时会出错，提示“illegal use ...
intmain() { inta[10000],i,n,key; printf("Enter size of the array : "); scanf("%d",&n); printf("Enter elements in array : "); for(i=0;i<n;i++) { scanf("%d",&a[i]); } sort(a,n); print(a,n); } Output:
函数代码如下：void sort(int a[], int n){int i, j, m;int temp; for(i = 0; i < n -1; i++){m = i;for(j = i + 1; j < n; j++){if(a[j] < a[m])m = j;}if(m != i){temp = a[i];a[i] = a[m];a[m] = temp;}}}整个测试如下：include <...
