Simple Program for Read File Operation

Program for reading the content of a file.

Simple Program for Read File Operation Algorithm/Steps:

• STEP 1: Start the program.
• STEP 2: Declare the variables.
• STEP 3: Get the file name to read.
• STEP 4: Using ifstreamin(filename) check whether the file exist.
• STEP 5: If the file exists then check for the end of file condition.
• STEP 6: Read the contents of the file.
• STEP 7: Print the contents of the file.
• STEP 8: Stop the program.

Simple Program for Reading File Operation Example

#include<iostream.h>
#include<conio.h>
#include<fstream.h>

void main() {
    char c, fname[10];
    clrscr();
    cout << "Enter file name:";
    cin>>fname;
    ifstream in(fname);
    if (!in) {
        cout << "File Does not Exist";
        getch();
        return;
    }
    cout << "\n\n";
    while (in.eof() == 0) {
        in.get(c);
        cout << c;
    }
    getch();
}

Sample Output

Enter File name: one.txt
