13. 数组

代码语言:javascript复制
#include"stdio.h"
main()
{
    int j,k;
    static int x[4][4],y[4][4];
    for(j=0;j<4;j  )
        for(k=j;k<4;k  )
            x[j][k]=j k;
    for(j=0;j<4;j  )
        for(k=j;k<4;k  )
            y[k][j]=x[j][k];
    for(j=0;j<4;j  )
        for(k=0;k<4;k  )
            printf("%d,",y[j][k]);
}

运行结果为:

0,0,0,0,1,2,0,0,2,3,4,0,3,4,5,6

函数

1.

代码语言:javascript复制
#include <stdio.h>
int Sub(int a, int b)
{
    return (a- b);
}
main()
{
    int  x, y, result = 0; 
    scanf("%d,%d", &x,&y );
    result = Sub(x,y ) ;
    printf("result = %dn",result);
}

当从键盘输入:6,3运行结果为:

result =3

2.

代码语言:javascript复制
#include <stdio.h>
int  min( int x, int y ) 
{ 
    int  m;
    if  ( x> y )  
        m = x;
    else             
        m = y;
    return(m);   
}
main()
{
    int  a=3,b=5,abmin; 
    abmin = min(a,b); 
    printf("min  is  %d", abmin);
}

运行结果为:

min is 5
