I need to take input from the user that is a single line and has 5 values which I extract from that input ('c' needs to be 5). The input is this format: "word(number) number word sentence". But the problem is with the "word(number)" input area. I cannot get it so that the values are read from that part of the input and stored in command, and num1. Below is the code I tried but it does not seem to be working.

c = sscanf (line, "%s(%d) %d %s 8[^\n]", command, num1, num2, message, message2);

When I make it so that the user enters "word (number) number word sentence" instead, with a space before the brackets, with also changing the code from %s(%d) to %s (%d), that seems to work. But I need it without any space between the values command and num1.

You will need to exclude the parenthesis from the first string. Assuming the "command" is strictly alphanumeric and underscore, you can do this:

c = sscanf(line, "%[_a-zA-Z0-9](%d) %d %s 8[^\n]", command, &num1, &num2, message, message2);

Also, you need ampersands on num1 and num2; perhaps those were typos?

For safety, you should put length limits on command and message as you do for message2. Assuming 'char command[21], message[33];`, this would be:

" [_a-zA-Z0-9](%d) %d 2s 8[^\n]"
