C语言实现int转换string

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

int string2int(const char * string)
{
    ;
    ;
    '; index ++)
    {
        value = value *  + ';
    }
    return value;
}

int string_reverse(char * strSrc)
{
    ;
    ;
    char * output = NULL;
    char * pstr = strSrc;
    while(* pstr)
    {
        pstr++;
        len++;
    }
    output = (char *)malloc(len);
    if(output == NULL)
    {
        perror("malloc");
        ;
    }
    ; i < len ;i++)
    {
        output[i] = strSrc[len - i -];
        printf(,strSrc[len - i - ]);
    }
    output[len] = '\0';
    strcpy(strSrc, output);
    ;
}

int  int2string(int value, char * output)
{
    ;
    )
    {
        output[] = value + ';

    }
    else
    {
        while(value)
        {
            output[index] = value %  + ';
