将字符串数组转换成大字符串，用逗号分隔

/*string[] stringArry,将字符串数组转换成大字符串，用逗号分隔
比如：string[2] stringArry= {“123”, “abc”}，转换成string strs = “123,abc”*/
#include<stdio.h>
#include<string.h>
#define N 4
void main()
{
char *stringArry[N]= {"123","abc","aasdasdsddddd1222bc","asdsadasd"};
char str[100]="",*d=str;
int i;
for(i=0;i<N;i++)
sprintf(d+strlen(str),"%s,",stringArry[i]);
str[strlen(str)-1]='\0';
printf("%s\n",str);
}

或:
#define N 256
char strs[N];

memset(strs, 0x0, N);
strcat(strs, stringArray[0]);
strcat(strs, ",");
strcat(strs, stringArray[1]);
