write a C program that read data from file data.in and store in an array.
a) find the name entered from keyboard. If no match then return "Not found"
b) list all names that are not duplicate in array
data.in file content:
5
Bill Gates
Steve Jobs
Daniel Rhode
Billy Carpenter
Steve Jobs
when i typed in the name, the output was always not found even when matched. What is the problem here??
This line
if(index == num)
printf("\n%s Not Found in array",name);
index == num will be true always.
The problem is that the fgets that reads from the file data.in includes the trailing newline on each line, whereas the gets from stdin does not include the trailing newline. That is why there is no match.
You can read more about the trailing newline problem here: Removing trailing newline character from fgets() input
And, as others have pointed out, you need to break from the loop when you find a match.
fgets, which leaves the newline at the end of the string. But you read the name to search for withgets, which does not leave the newline. One fix is to usefgetsto read the name to search for.
