    need help on string compare

    i stumble onto a problem on comparing strings
    can someone help me again? I have manage the checking on the string of input but i cant seem to code the correct part on comparing M and F, its about the gender input. User can only input M,m,F or f.
    PHP Code:
    void val_gen(void)
    {
        
    char msg[]="Invalid Input!!! Accepts only M or F only";
        
    char v_flag;
        do
        {
            
    gotoxy(45,15); clreol();
            
    fflush(stdin);
            
    gets(mem_temp.mem_gen);
            
    v_flag val_gsize(1mem_temp.mem_gen);
            if (
    v_flag =='Y')
            {
                
    v_flag=val_gchar(mem_temp.mem_gen);

                if(
    v_flag=='N')
                
    err_msg(msg);
            }
        }
        while (
    v_flag=='N');
        
    caps_str(mem_temp.mem_gen);

            if (strcmp(text, "m") != 0 && strcmp(text,"f") != 0)
                status = 'N';

    char val_gchar(char text[])
    {
      if (
    strcmp(text"m") !=&& strcmp(text,"f") !=0)
                return 
    'N';
            else
                return 
    'Y';
