(2) Using the survey results and the answer from part 1, complete the Venn diagram below. Computer Science Engineering Mathematics (3) How many: students study all three subjects? How many study only Mathematics? Please help! I have to write a program in C--that takes the following "Node A" table (shown at the end of this page) from a file called "node_a.txt", and saves it into an array. The array should later on be accessed, and all the columns should easily be displayed in the program just like the way its shown on the table. However, my "node_a.txt" file is in the following format: node AB 6 - SC1-SD 6 B SE 6 BSF 2 - FG 2-F and CAN NOT be modified in any way, it should stay that way. If someone can help me out, I would really appreciate it. Node A Destination Line Cost Next node Link status B 6 S C 1 S DEFG 6 B S 6 B S 2 F 2 F
