for those people who are good in making a visual studio C++ program.. I need some help for my project about creating a program that will convert dollar value into peso and vice versa.

Please don't ask us to do your homework for you! :-(

Visual Studio C++ aside, the code will be common to all C++ compilers. Read the VS documentation and then write the code. At that point, if you have problems, we might be able to help you.

BTW, which country's peso are you referring to? Today, Mexico's peso to US dollar rate is 7.7 cents to the peso, so the math is this:

dollars = 0.077 * pesos
pesos = dollars / 0.077

Very basic math. Now, write the code to input dollars or pesos, and to convert one to the other.
