Project 1, COP 3514, summer 09

Write a C program that asks the user to enter a positive integer (the integer could be of any number of digits in the range of the integer type) and replace each digit by the sum of that digit plus 6 modulus 10. The program then should swap the first digit with the last digit before it displays the output. Must follow the instructions in the attached doc. Ignore the first part of the project(barcode2.c).

 

 

Project 6, Program Design 1. (30 points) Note: This program will be graded based on whether the required functionality were implemented correctly instead of whether it produces the correct output, for the functionality part (80% of the grade). Modifybarcode.c(atached, ProjecT 4, #2), The edge deTec±on func±on using poinTer ariThme±c. ²he func±on proToType shouldbe The following. Name your programbarcode2.c.void edge(int n, int *a1, int *a2);The function should use pointer arithmetic – not subscripting – to visit array elements. In other words, eliminate the loop index variables and all use of the [] operator in the function. 2. (70 points) Write a C program that asks the user to enter a positive integer (the integer could be of any number of digits in the rangeof the integer type) and replace each digit bythe sum of that digit plus 6 modulus 10. The program then should swap the first digitwith the last digit before it displays the output.
