1、我们在main函数之前定义一个函数。
2、然后我们就可以开始编写，并且先输入整个框架。
3、然后我们可以用和循环开始进行输出。
4、利用普通变量也可以使用指针变量来书写。
5、在这里我们将以指针变量来书写。
6、书写完毕后，我们将可回去main函数中进行直接调用。
你可以写一个探测字符长度的函数:
# include <stdio.h>
//获取字符长度的函数:
int GetCharLong(char * C_P) {
int aa = 0;
while (1) {
if (*C_P == '\0') {
return aa;
}
C_P++;
aa++;
}
}
int main{
char a []="abc123";
char b []="123defw";
int aa = GetCharLong(a);
int bb = GetCharLong(b);
if (aa > bb){
printf("第一串长！%s\n", a);
}
else if (aa < bb){
printf("第二串长！%s\n", b);
}
else{
printf("两串字符一样长！");
}
return 0;
}
int strcmp(char *s,char *t)
{
for(;*s&&*t&&*s++==*t++;);
return(*s-*t);
}
#include<stdio.h>
#include<malloc.h>
#include<string.h>
int main()
{char *p[20];
int n,i,max=0,maxi=0;
scanf("%d",&n);
for(i=0;i<n;i++)
{
p[i]=(char *)malloc(20);
scanf("%s",p[i]);
if(strlen(p[i])>max)
{
max=strlen(p[i]);
maxi=i;
}
}
printf("
%s
",p[maxi]);
return 0;
}
#include<stdio.h>
#include <string.h>
int main (void)
{
int n;
char str[1000];
char Max[1000];
scanf ("%d", &n);
for(int i = 0; i < n; i++)
{
scanf("%s", &str);
if(i==0) strcpy(Max, str);
if (strlen(Max)<strlen(str))
{
strcpy(Max, str);
}
}
printf ("The longest is: %s", Max);
return 0;
}
