以逗号分割字符串，形成二维数组，并把结果传出C/C++

有一个字符串符合以下特征（”abcdef,acccd,eeee,aaaa,e3eeeee,sssss,”;）,要求写一个函数（接口），输出以下结果

1） 以逗号分割字符串，形成二维数组，并把结果传出；

2） 把二维数组行数运算结果也传出。

int getStrArray(const char *src, char dst[100][100])      
{      
    int i = 0,j = 0, nLength  = 0;      
    char *curStart = src; 
    char *lastStart = src;

    do 
    {
        curStart = strstr(curStart, ",");
        nLength = curStart - lastStart;  
        memcpy(dst[i++], lastStart, nLength);      
        lastStart = ++curStart;      
    } while (*curStart != '\0');   
    return 0;      
}      
int main()      
{      
    char *src = "abcdef,acccd,eeee,aaaa,e3eeeee,sssss,";      
    char dst[100][100] = {0};      
    getStrArray(src, dst);      
    return 0;      
}  

还可以用另外一种二维指针模型来实现 二维指针共有三种

void printfArr(char **arrayPtr, int nLength)  
{  
    int i = 0;  
    for (; i < nLength; i++)  
    {  
        printf("%s\n", arrayPtr[i]);  
    }  
}  


int getStrArray(const char *src, char **dst)      
{      
    int i = 0,j = 0, nLength  = 0;      
    char *curStart = src; 
    char *lastStart = src;

do 
{
    curStart = strstr(curStart, ",");
    nLength = curStart - lastStart;  
    memcpy(dst[i++], lastStart, nLength);      
    lastStart = ++curStart;      
} while (*curStart != '\0');   
return 0;      


}      

int main() 

{ 

    int j = 0; 

    int i =0; 

    char *src = “abcdef,acccd,eeee,aaaa,e3eeeee,sssss,”; 

    char dst = (char )malloc(10 * sizeof(char *));

if (!dst)
{
    return -1;
}
for (; i < 10; i++)
{
    dst[i] = (char *)malloc(100);
    memset(dst[i],'\0',100);
}

getStrArray(src, dst); 

printfArr(dst, 10);

for (i = 0; i < 10; i++)
{
    free(dst[i]);
}
free(dst);
return 0;      


} 

//获取总共要分几行 

void getLine(char *str, char c, int *line){ 

    char *p = str; 

    char *q = str; 

    int num = 0; 

    while (*p != ‘\0’){ 

        if (*p == c){ 

            num++; 

        } 

        p++; 

    } 

    num = num + 1; 

    *line = num; 

} 

char **  getData(char *str, char c, int line){ 

    char *p = str; 

    char *q = str;

char **result = (char **)malloc(line*sizeof(char*));
for (int i = 0; i < line; i++){
    while (*q != '\0' && *q != c){//没有到字符串的结尾或者遇到分割符c
        q++;
    }
    char *part = (char *)malloc(100 * sizeof(char));
    int length = q - p;
    memcpy(part, p, length);//拷贝数据
    part[length] = '\0';

    p = q + 1 ;
    q = q + 1;
    result[i] = part;       
}
return result;


};

void main(){ 

    char *str =”abcdef,acccd,eeee,aaaa,e3eeeee,sssss”; 

    int line = (int )malloc(1*sizeof(int)); 

    char c = ‘,’; 

    getLine(str, c, line); 

    printf(“%s字符串可以分%d行\n”,str,*line); 

    char ** result = getData(str, c, *line); 

    printf(“分割的字符串数组数据:\n”); 

    for (int i = 0; i < *line; i++){ 

        printf(“%s\n”,result[i]); 

    } 

    system(“pause”);
