Visual C++ :: Print Dash After Every 3 Numbers From ID

Dec 7, 2013

I am currently working on a student records program and I want it to print a '-' after every 3 digits from the Id number that I read from the file(ID number from file doesn't have the dashes). How would I do that to print it with dashes?

Here are my reading functions.

Code:
void Read_Student(Student & Temp , ifstream & fin){

fin >> Temp.FirstName;
fin >> Temp.LastName;
fin >> Temp.Id;
fin >> Temp.Quiz;
for (int i = 0 ; i < 6 ; i++)
fin >> Temp.Test[i];

[Code] ....

One more thing, I also am having problems with reading last name. If I edited the inout file and had for example John Adams Jr. it would cause huge print problems. When I remove it it prints out perfectly.

C++ :: Print All The Whole Numbers From 1 To N

Feb 17, 2012

I did write a print function which the user put a number and then it will print out till that number

the output is correct ,, but is code correct ? or it could be better somehow ?

write a function named print_out that print all the whole numbers from 1 to n. test the function by placing it in a program that passes a number n to print_out , where this number is entered from the keyboard . the print_out function should have type void; it does not return a value. the function can be called with a simple statement:

print_out(n);

PHP Code:

# include <iostream>
using namespace std;
void print_out (int x);
int main () {
    int n;
    cout << " enter a number : ";

[Code] ....

C++ :: Print All 64-bit Binary Numbers

Jul 31, 2013

I have a program in c++ to print all the binary numbers that have 64 bits. But the problem is it works only for 30 bits. Beyond that the program does not work possibly because of insufficient space availability.

my code is as below:

// C++ program to generate n-bit binary numbers
#include <iostream>
#include <string>
#include <vector>
#include <fstream>
using namespace std;

// This function generates all n bit Gray codes and prints the generated codes

C :: Program To Print All Of Prime Numbers To Screen

May 29, 2013

I'm trying to write a program that prints all of the prime numbers to the screen. I'm getting angry because it only prints EVERY number. I think it has something to do with the bool change not being able to leave the for-loop but how to fix it.

Code:
#import <stdio.h>
#include <stdbool.h>
int main(void){
printf("
The Primes Are: 1");

C :: Print All Numbers Up To The Inputted Number Vertically

Feb 19, 2013

I've written a program which takes a character string and then prints each character vertically so that for instance the string 123 can be written as
1
2
3

no what i need is for all the numbers from zero to the inputted number to print the numbers digits vertically but each number to be printed horizontally so that for instance an input of 11 prints

1 2 3 4 5 6 7 8 9 1 1
0 1

i've made it so that i can print all numbers up to the inputted number vertically; however, i am stuck with a method for making each number print horizontally as described above.

C++ :: Find And Print Average Of Odd Numbers Greater Than 5 And Less Than 100

Nov 5, 2014

I am new to programming in C++, and have got a project on this.

Write a C++ program that accepts three numbers from the user (All are integers):

Such as:

Enter the first mark: 3
Enter the second mark: 25
Enter the third mark: 23

The program should find and print the average of the odd numbers greater than 5 and less than 100.

C++ :: Function To Determine And Print Prime Numbers

Mar 30, 2013

/* Task: create a function that determines prime number and use it to print out prime numbers from 0-50: */

Function prototype: Should return a `bool` (because it answers a yes/no question) and should take in a single int (to ask whether it's prime).

- An int greater than 2 is prime if it is not divisible by any number between 2 and itself, not including itself.
- Use this function to print out the primes less than 50. Check it against my list:
2 3 5 7 11 13 17 19 23 29 31 37 41 43 47

#include <iostream>
using namespace std;
int prime(int&x) {
if(x%2==1)

[Code] ....

It is printing out the correct prime numbers but also printing this between each number: 1629974960

C++ :: Print Numbers At Random From A Set Using Single Statement

Jan 21, 2012

I have an exercise that asks me to print numbers at random from the following set (using only a single statement):

2, 4, 6, 8, 10

Here's my statement:

Code:
cout << (2 + rand() % 9) << " ";

which prints numbers at random between 2 and 10, now I can use the modulus operator in an if...else statement to print only even numbers but the exercise specifically requires using only one statement, can that be done using the conditional operator? and if not then how?

C :: Print Listing With Line Numbers - Cannot Execute / Run Program

Feb 18, 2013

The problem is with the first "Type and Run," where the code looks like this:

Code:
/* print_it.c--This program prints a listing with line numbers! */
#include <stdlib.h>
#include <stdio.h>

void do_heading(char *filename);
int line = 0, page = 0;

[Code] ....

I am using the gcc compiler in Ubuntu 12.04 LTS and I get the following error:

Code:
print_it.c: In function "main":
print_it.c:36:15: error: "stdprn" undeclared (first use in this function)
print_it.c:36:15: note: each undeclared identifier is reported only once for each function it appears in
print_it.c: In function "do_heading":
print_it.c:49:16: error: "stdprn" undeclared (first use in this function)

I was told that "stdprn" can be recognised by a DOS based compiler and the book says I can try using "stdout" instead. It looks like this now:

Code:
/* print_it.c--This program prints a listing with line numbers! */
#include <stdlib.h>
#include <stdio.h>

void do_heading(char *filename);
int line = 0, page = 0;

[Code] .....

It compiled OK with the gcc compiler but I only get this when I run the program:

Code:
Proper Usage is:
print_it filename.ext

I am not sure whether I should continue looking into this but even when I tried compiling and running it on Windows, the .exe file won't even launch. The other ones do but this first one doesn't.

Questions:

1. What should be done to make this program run?
2. Even though the book says "don't care" if the reader does not understand the items (It's Day 1/Lesson 1), I would still like it to run as I don't want to experience compiling and running problems in the future. Should I even bother doing this section of the book or is it obsolete and should be skipped?

C++ :: Pass Array Of Int And Its Size - Print Out Numbers Above Average

Nov 15, 2013

I am attempting to write a program " that has a function that is passed an array of int and its size, and with that it prints out only the numbers that are above average. "

I have included my code so far, but I am only getting one value as output, and that value seems to be completely off. I keep trying, but I am really stuck.

#include <iostream>
using namespace std;
int average(int values[],int size);
int main(){
int size;
int values[] = {1,2,3,4,5,6};

[Code] ....

Added the floats in the average() function. But there is still a value problem.

C/C++ :: Program That Will Print Numbers In Columns From User Input

Oct 7, 2014

I tried to work on this program for while, but I am not able to get it to work

Directions:Write a program that reads an integer n from the user.

Display the first 100 numbers, with newlines every n numbers, using % operator

#include <stdio.h>
int main(void){
int a = 0;
int b = 99;
printf("Enter a number: ");
scanf ("%d", &a);

[Code] ....

When I run this code it asks me to enter a number. It doesn't matter what number I enter it gives me the numbers from 1 to 100 in one horizontal line.

I want this program to do something like this:

for example if the user enters n=6 the program should give:

0 1 2 3 4 5 6
7 8 9 10 11 12 13
and so on
