Answer:
cin.ignore(100,'\n') >> c;
Explanation:
In order to read data in C language, cin >> variable_name is used. In the question it is also asked that we should read until the next line, assuming the input is under 100 characters long.
If we use cin.ignore(100, '\n'), this will enable us to read until the next line. It will ignore first 100 character, and stop reading data when it reaches '\n' (in this case stopping criteria is being at the end of the line).
