The object of the project is to create an application that can calculate math tables.
The Math Table using the ‘C’ application is created to make students’ maths skills better. The application or program created from this project includes the option like to enter the user name, the option to practice table, the option to choose a table for practice, the option to check whether the answer is right or wrong and correct it, show the number of wrongs and right answer, and final option to practice again.
The project Advance Math Table is based on C and the code for the program is:
