c語(yǔ)言編程寫一個(gè)函數(shù),返回三個(gè)整數(shù)中的中間數(shù)

只有3個(gè)數(shù)，窮舉比較實(shí)現(xiàn)很方便，所以在輸入3個(gè)數(shù)后直接利用if...else if結(jié)構(gòu)比較大小取中值輸出即可。代碼如下：

#include?"stdio.h"

int?main(int?argc,char?*argv[]){

int?a,b,c;

printf("Input?3?integers...\n");

scanf("%d%d%d",a,b,c);

printf("In?the?middle?of?the?number?is?");

if(a=b??b=c?||?c=b??b=a)

printf("%d\n",b);

else?if(b=a??a=c?||?c=a??a=b)

printf("%d\n",a);

else

printf("%d\n",c);

return?0;

}

運(yùn)行樣例如下：

c程序：給出A,B,C尋找中位數(shù)

沒(méi)有包含頭文件conio.h，

還有倒數(shù)第三行改為printf("%d\n",zws(a,b,c));

#includeconio.h

#includestdio.h

int zws(int a, int b, int c){

int ans;

if (a = b a = c) ans = a;

if (a = b a = c) ans = a;

if (b = a b = c) ans = b;

if (b = a b = c) ans = b;

if (c = a c = b) ans = c;

if (c = a c = b) ans = c;

return ans;

}

int main()

{

int a, b, c;

printf("please input 3 integar:");

scanf("%d %d %d", a, b, c);

printf("%d\n",zws(a, b, c));

getch();

}
