For your lab assignment, you will write a program called lab4.c that will print out the values for Pascal's Triangle, in triangular shape, using input from the user for the number of rows. The formula for generating the numbers of Pascal's Triangle is: coefficient = (coefficient * (i - j) / ( + 1)) where the coefficient is initialized to 1 within the for loop in which i is the loop control variable. For printing the elements, another nested for loop with loop control variable of j is used. Use a width of 3 for the values being printed. Example output should look similar to the following (user input in bold): How many rows for Pascal's Triangle? 5 1 1 1 1 2 1 1 3 3 1 1 4 6 4 1
