The task is trivial but i don't know why the first time it send me compilation error - it doesnt see why?
for(int i = 0 ; i < strlen(line) ; i++)
        {
        if(!isalpha((int)line[i]))
        {

        if(started)
        {
        for(int z = i - 1 ; z >= startPos ; z--)
                cout << line[z];


#### that is some part of my code and it gave me compliation error because in int z = i - 1 z is undefined?
