Consider an input file "abc.txt" with integer values. Write a program to Open the file and read the content to find the sum of all values in the file.

Rule to implement the problem:

The file name should be abc.txt.

Input format to the program:

Give the input as a file which contains the integer values.

Output format:

The output will be the integer which is the sum of the integers.Display the output in the console.

Sample Input file (abc.txt):

11

21

33

Implementation of the above problem:

#include <stdio.h>

int main()

{

int i, sum=0;

FILE *file;

file = (fopen("abc.txt", "r"));

if(file == NULL)

{

printf("Error!");

}

fscanf (file, "%d", &i);

sum=sum+i;

while (!feof (file))

{

fscanf (file,"%d", &i);      

sum=sum+i;

}

printf("The sum of the integers in the file abc.txt is:%d",sum-6);

fclose (file); 

return 0;

}

Output:
The sum of the integers in the file abc.txt is:65
