text files

[cv87cv]

I am trying to answer a question with regards to entering a set of numbers and text, and then I have got to search for a number and the text with it.

This is the code that I have written for inputting the numbers:

#include "stdafx.h"
#include <iostream>
#include <fstream>
#include <stdio.h>
using namespace std;

int main()
{
char name[20];
int mark;
int x;
FILE *f;
f = fopen("black.txt","w");
for(x=1; x<=5; x++)
{
printf("Enter a name \n");
gets(name);
printf("Enter a mark \n");
scanf("%d",&mark);
fprintf(f,"%s %d\n",name, mark);
}

fclose(f);
return 0;
}

it will not input the number and mark correctly together

the other part of the code to display a certain number and text is :


#include "stdafx.h"
#include <iostream>
#include <fstream>
#include <stdio.h>
using namespace std;

int main()
{
char name[20];
int number;
int x;
FILE *f;
f = fopen("black.txt","w");
while ( fscanf(f,”%s”,name )
{
if (number=10)
{
printf(“%s \n”,name);
}
}
fclose(f);
return 0;
}

this part is not working properly either and I am unable to spot what is wrong with it. i think because i've been looking at it for a while i just cant see the problems

so if someone can help me that would be great

how do you want to format the name and mark because that determines how you read the information, e.g.
(1) two lines
Sam Jones
45
(2) one line
Sam Jones 45

will you always have a fist name and last name, can you have a middle name, etc?

yea there will always be a first and last name, no middle name. the name will be on a different line to the number which is given to each person.

you could have seperate variables for first and last name, e.g.

#include <stdio.h>
 
int main()
{
char firstname[20],lastname[20];
int mark;
int x;
FILE *f;
f = fopen("black.txt","w");
for(x=1; x<=5; x++)
{
printf("Enter a name \n");
scanf("%s%s",firstname, lastname);
printf("Enter a mark \n");
scanf("%d",&mark);
fprintf(f,"%s %s mark %d\n",firstname, lastname, mark);
}
fclose(f);
return 0;
} 
 

are you planning to use C or C++ as you had included header files from both?
