I want to create three files whose names are same but extensions are different. I have to take the name from user. I tried following code but it didn't worked ...
Code:
printf("Name of the file:"); scanf("%s",name);
printf("Format of Input file:");
scanf("%s",ext);
f1=fopen(name.ext,"r");
f2=fopen(name.dat,"w");
f3=fopen(name.src,"w");
f4=fopen(name.RMH,"w");
I need to create a program that will prompt the user for an input, then it will save their input to a file and then it will prompt the user to input "Open" and then the file containing their first input, will open up and show their input.

What I want to do is create a file that will ask the user to enter his info,n then store it in a text file The screen will ask the user if he wants to update his info. if he says yes then the screen will be cleared and the old info will be printed on the screen. The user will enter his new info that will be stored in a new file. My problem is that once the user finishes entering his input the program just closes D: and the rest of the program won't run.

I am a beginner with C++, taking a class right now. The lab this week is to create a user defined class and have it accesses in a separate .h header file from the main.
I think I'm finding my way through it, but I'm getting a complie error that makes no sense to me:

I'm creating a program that should create a structure of a list of people entered by the user; the only problem I'm having is with the %c. When I have it, the loop only occurs once; if I put a %s, the loop occurs up to 25 times, but it doesn't write to the text file. Here is the code:

How to open a file that the user input

I'm trying to develop a programme which, amongst other things, prompts the user to enter the filename which is to be opened. This is what my code looks like currently:
char filename[20];
FILE *myfile;
printf("Enter the full file name you would like to open:");
scanf("%s", filename);

However, this only ever returns File Not Found - the file is stored in the same directory as the program, and I have tried looking up this issue online, to no avail ....
This program will allow the user to input string then scans the file if it contains the same string given by the user. But i always get "MATCHED" even if i enter random string. I tried and tried to place the if statement in different positions but i dont get my expected output.

So I'm writing a program that will read a text file and it will do certain "functions" the text file will be like a game, and the program will be able to run many different games. The problem i'm having is in one of the "functions" i believe it's the one meant to get a correct choice from a file and a user input and put them into strings, it gets the wrong input. I know this because i tested both strings the "function" writes too. it gets the correct file answer but the user input is always "c" for some reason.

#include <iostream>
#include <iomanip>
#include <fstream>

This is the code, most likely the section that is surrounded with "///" contains the problematic "functions." This is the command Line output...investigate why they're dieing or continue on your journey?(i-investigate/c-continue) got input and answer
i
c
i
Press any key to continue . . .
The got input and answer are tests to make sure it got both, the first 'i' is my input, the 'c' is what it says my input is, and the 'i' is the correct answer from the file. this is the part of the file that the program reads to get that output
"1 Do you want to go investigate why they're dieing or continue on your journey?(i-investigate/c-continue) 2 8 i 7 3 4 You continue on picking up speed to get to the egg first.. and.. Oh No, You accidentally bumped into the walls! 2 12 5 1 You go over, and as you realize the walls are acidic and that's why the other sperm are dieing.. 2 6"

How to get this thing to work. All i need to do is ask user to input a name and then it brings out the line from the .txt file containing the information.

Write a program to generate a report based on input received from a text file. Suppose the input text file student_status.txt contains the student’s name (lastName, firstName middleName), id, number of credits earned as follows :
Doe, John K.
3460 25
Andrews, Susan S.
3987 72
Monroe, Marylin
2298 87
Gaston, Arthur C.
2894 110
Generate the output in the following format :
John K. Doe 3460 25 Freshman
Susan S. Andrews 3987 40 Sophomore
Marylin Monroe 2298 87 Junior
Arthur C. Gaston 2894 110 Senior
The program must be written to use the enum class_level :
enum class_level {FRESHMAN, SOPHOMORE, JUNIOR, SENIOR } ;
and define two namespace globalTypes (tys and fys) for the function :
class_level deriveClassLevel(int num_of_credits) ;
The function deriveClassLevel should derive the class_level of the student based on the number of credits earned.
The first namespace globalType tys should derive the class level based on a two year school policy.
and the second namespace globalType fys should derive the class level based on a four year school policy.
Four Year School Policy:
Freshman 0-29 creditsSophomore 30-59 credits
Junior 60-89 creditsSenior 90 or more credits
Two Year School Policy:
Freshman 0-29 creditsSophomore 30 or more credits
NOTE : use ignore() function with ifstream objects whenever you want to ignore the newline character.
For example :
ifstream transferSchoolFile ;
transferSchoolFile.open("student_status.txt", ios::in);
while( !transferSchoolFile.eof()) {
getline(transferSchoolFile,name) ;
transferSchoolFile >> id >> credits;
transferSchoolFile.ignore(); //Used here to ignore the newline character.
….
}
I did this in parts so I got it working with a four year criteria without the user defined name spaces.
include <iostream>
#include <fstream>
#include <string>
using namespace std;
enum class_level { FRESHMAN, SOPHOMORE, JUNIOR, SENIOR };
[Code] ....
So that worked fine then I tried with name spaces -
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
enum class_level { FRESHMAN, SOPHOMORE, JUNIOR, SENIOR };
class_level classLevel;
[Code] ....
