Question

I want to extract some numbers from the input line which is a string. The string looks like this:

    command 1 2 3 4 5

So far i’ve done this but it is not working properly:

   if ( strncmp(line,"command",7) == 0 ){
          char *p = strtok(line," ");
          while ( p !=NULL){
                param1 = atoi(p[1]);
                param2 = atoi(p[2]);
                param3 = atoi(p[3]);
                param4 = atoi(p[4]);
                param5 = atoi(p[5]);
                p = strtok(NULL," ");
          }
   }

Where am i wrong ?

Using sscanf might be simpler:

if (strncmp(line, "command", 7) == 0)
{
    sscanf(&line[8], "%d %d %d %d %d", &param1, &param2, &param3, &param4, &param5);
}
