LAB #4: Solve the following questions in C language programming Lab p-1) Write a program that calculates the following math equation: laxb 5 a=30, b=23, c=13 Lab p-2) Write a program that prints an mxn matrix whose dimensions are specified by the user. Let the matrix values be random variables. You must use it within the repetition cycle. Example format: Enter dimension of matrix mxn: 24 The 2x4 matrix is : 1234 5678 Labp-3) Lab p-4) Lab p-5) Write a program that does factorial calculation in a recursive way. (not: recursive topic will not be in midterm exam) Write a program that prints the sum of the even numbers and the products of odd numbers on the screen. Create an mxn (user-defined) factorial matrix using the Rand () function. Make sure the Rand () function is not repeated. The factorial must be computed in a separate function. The factorial matrices can be seen below: (rand() variable range is 0-100) 4! 5! 3! 3! 1! 2! 9! 7! Calculate the factorials for the final display on the screen. You have permission to specify any range of random variables
