FILE
ReplyDeleteAim: Write a program to find the average of data in a file and print to another file.
Algorithm
1. Declare two pointers of structure FILE for input and output files
2. Use fopen() to read contents of a input file using read “r” mode
3. Use fopen() to write results to output file using write “w” mode
4. Use fscanf() to read data from the input file
5. Find the average of numbers in input file
6. Use fprintf() to write the results to output file
7. Use fclose() to close both FILE pointers
FUNCTION
Aim: Write a function to compute sum of integers.
Input two numbers that represent a range of integers and display the sum of the integers that lies in that range.
Algorithm
1. Prompt user and read the first number
2. Prompt user and read the second number
3. Calculate the sum of integers in the range smaller...larger by adding in turn each integer in that range
4. Display the sum
5. Find the average of data in a file and print to another file.
