1. Design a Ctt program named (permu_combi.cppl, present a menu to select from the program calculate permutation or combination for two integers, as example The menu will show: Please select: 1. Calculate Permutation 2. Calculate Combination 0. Exit Notes: Permutation P formula is: P(ab (a-b) P(a,b) Where x!- (x)- (x-1)-(x- 2).. 3) (2) (1) Break the program into functions/sub-components, at least 3 (main as default, permutation calculation, and combination calculation) These functions/sub-components must all have the appropriate parameters Upload the Ct+ source file (permu_combi.cpp), Upload a word document that contains: a. What is the program exactly do, b. Explanation of each sub-component, and c. Pseudocode for the program (Pseudocode (pronounced SOO-doh-kohd) isa detailed yet readable description of what a computer program or algorithm must do, expressed in a formally-styled natural language rather than in a programming language ) No Partial credit will be given, the uploaded must run for any credit. 10 Bonus points will be given for using function prototypes and header files (make sure you upload all files (driver .cpp, implementation .cpp, and header .h..e 3 files) and explain how to compile and link them)
