In C programming lanuage.

A. Given int variables k and total that have already been declared, use a while loop to compute the sum of the squares of the first 50 positive integers and store this value in total. Thus your code should put 1*1 +2"2+ 3*3 +... +49 49 50"50 into total. Use no variables other than k and total. B. Given int variables k and total that have already been declared, use a do... while oop to compute the sum of the squares of the first 50 positive integers and store this value in total. Thus your code should put 1*1 +2*2+ 3*3 +... 49*49+50"50 into total. Use no variables other than k and total. C. Given an int variable n that has been initialized to a positive value and, in addition, int variables k and total that have already been declared, use a while loop to compute the sum of the cubes of the first n whole numbers, and store this value in total. Thus if n equals4, your code should put 111+2*2*2+ 3*3*3 +4 4*4 into total. Use no variables other than n, k, and total. D. Given an int variable n that has been initialized to a positive value and, in addition, int variables k and total that have already been declared, use a do...while loop to compute the sum of the cubes of the first n whole numbers, and store this value in total. Thus if n equals 4, your code should put 1*1*1 +2*2*2+ 3*3*3 +4*4*4 into total. Use no variables other than n, k, and total
