c# using printf and scanf

Question 2: [4 Points] Write a complete C program consisting of a main and a function named FindCommon that do the following: FindCommon takes three integer arrays A, B and C and their size (they all have the same size). It then finds the common elements (Sllusliell) between A and B and stores them into C. FindCommon then returns the number of elements stored in C. For example, if A is [5 3 4 7 2] and B is [2 5 8 4 6], FindCommon stores [5 4 2] in C and returns 3 (the number of common elements that it stored in C). The order of elements in C does not matter, and it will be OK if C has duplication (15). The main creates three arrays A, B and C with size 1000 and fills A and B with random numbers. The main then calls FindCommon and passes A, B, C and 1000 to it. The main finally prints the common elements that FindCommon stores in array C
