 程序代码：#include <stdio.h> #include <string.h> #define MAX_LENGTH 100 int main(int argc, const char * argv[]) { char b[MAX_LENGTH] = {}; char m[MAX_LENGTH] = {}; memset(b, 0, sizeof(char) * MAX_LENGTH); do { memset(m, 0, sizeof(char) * MAX_LENGTH); fgets(m, MAX_LENGTH, stdin); strcat(b, m); } while (m[0] != '\n'); puts(b); return 0; } [此贴子已经被作者于2020-6-2 23:24编辑过] |

但以下代码却无法实现这个功能，原因何在，应如何修改？代码如下：
程序代码：#include"stdio.h"
char *p(char *a,int n){
char *m;
int i;
i=n;
m=fgets(a,n,stdin);
while(a[i]!='\0'&&a[i]!=EOF){
while(a[i]=='\n'||a[i]=='\0'){
a[i]=',';
i++;
}
if(a[i]=='\n'||a[i]=='\0')
a[i]=',';
i++;
}
a[i]='\0';
return m;
}
int main(void){
char b[1000];
char *m;
m=p(b,1000);
puts(m);
return 0;
}
char *p(char *a,int n){
char *m;
int i;
i=n;
m=fgets(a,n,stdin);
while(a[i]!='\0'&&a[i]!=EOF){
while(a[i]=='\n'||a[i]=='\0'){
a[i]=',';
i++;
}
if(a[i]=='\n'||a[i]=='\0')
a[i]=',';
i++;
}
a[i]='\0';
return m;
}
int main(void){
char b[1000];
char *m;
m=p(b,1000);
puts(m);
return 0;
}
