2012-12-13T14:31:00.000-08:00

Make a program in which user enters a number n...If n is not integer, print a message about that and ask a user to enter a number again...User than enters n numbers, after that program prints an average of entered numbers....

Matrix 50 x 50 and secondary diagonal

2012-12-11T10:27:00.001-08:00

/*
Question:
Make a logic of program which will use a matrix [50][50]....User types the numbers, and numbers must be less or equal to 50, if that condition is not satisfied, you need to repeat the number m....Find and multiply the numbers on secondary diagonal of matrix....(secondary diagonal goes from upper right side to downer left)
