#c strcmp() isn't working as it should

问题:

I want to compare between two char* so i do it with strcmp, look, in debugging mode, both char* in strcmp gets the same value and still it wont return 0, and it jumps over the if() condition instead of entering it:

here pic from the debugger: http://img405.imageshack.us/img405/5218/111fi.jpg

Company FindCompany(CompanyL pcompanyList, int companyIdentityDigit) 
{
    Company companyFound;
    char *psearchWord;
    psearchWord = (char*)malloc(10*sizeof(char));

    switch(companyIdentityDigit) {
        case 0: 
            strcpy(psearchWord , "Pelephone");
            break;
        case 2: 
            strcpy(psearchWord , "Cellcom");
            break;
        case 4: 
            strcpy(psearchWord , "Orange");
            break;
    }

    while(pcompanyList->next != NULL)   {
        if(strcmp(pcompanyList->thisCompany->pcompany , psearchWord) == 0)  {
            free(psearchWord);
            return pcompanyList->thisCompany;
        }
        pcompanyList = pcompanyList->next;
    }
    free(psearchWord);
    return NULL;
}

why is it??

回答1:

Try a simple for loop to print out the characters in pcompanyList->thisCompany->pcompany one at a time:

for (int x = 0; x < strlen(pcompanyList->thisCompany->pcompany); x++)
    printf("%c ", pcompanyList->thisCompany->pcompany[x]);

You can do this or check the length of each string to make sure there aren't hidden characters that aren't showing up in the debugger when you check the strings.
