Link with C program, Help anybody?

Question

I have a C program that returns values of 4 statistic moments (mean, standard diviation, skewness, kurtosis) from a number of vectors. My purpose is making a C# program that calls the C program and prints out the 4 moments on C# window console. Since I have just started to learn C# program (it has been only a week), I am not sure where to look for an answer. I tried to find the answer through interoperability of C# but it was confusing. If you have something to clear me out, please let me know as soon as possible. I am tackling almost five days but I feel like I am getting nowhere. Thanks a million.
