My name is plawasha and i,m student of software engineering. but as i,m new in development i am learning about development how to develop a program and it is very tough to learn development in this age as i,m 21 year old so i,m working hard to learn about development and basically i,m student of economic and i start learning development due to my fiance and he is working with me to teach me how to develop a program.

I develop a program in C ++ and it has alot of error which compiler is not showing as the errors they are logical errors.
