I was trying to get the name of the user and print it but the only thing that i get is the first Character. For example, in this code, i try to get the name of the user and print it.
#include <iostream.h>
int main(){
char name;
cin >> char;
cout<< "welcome " << name;
return 0;
}
should i define "name" in another way?
The function uses a "for" loop to print the given character the number of times specified by the integer.
How can I make a for loop to do that?
So.. my code looks like this:
// cpp : Defines the entry point for the console application
//
#include "stdafx.h"
#include <iostream>
using namespace std;
void printMyInteger(int myInteger, char myChar) {
[Code] ....
So.. here is my error:
Error1error C2143: syntax error : missing ';' before ')'d:workspaceuniversity ools for games and animationworkshopsweek 6week 6week 6week 6.cpp101Week 6

How to do this?

This code work fine...but i want to take name from user..how i store it in character array through getline()..
Question simple like that: Let user enter some words from keyboard, one word per line until a '.' (period) entered then print out result, for example:
Code:
Enter a word: word1
Enter a word: word2
Enter a word: .
You have entered 2 word(s):
word1
word2
Problem is I don't know how to declare the array of character at the beginning since I don't know neither how many word user may enter nor how many letter of each word. So I go ahead and declared like this: char word[20][50] but I know it is not best way.
Code:
int main () {
char word[20][50]; //array has maximum 20 words, each word maximum 50 character
int i=0, number_of_word;
do {
printf ("Enter a word: ");
[Code] ....
I'm trying to get the hang of the declaration and use of char. I'm trying to write a program that reads sentences from the user and changes them based on their character choices, I keep getting load of compiler errors.......am I off to a good start or am I way off?

How can I create in my C++ program so a user can paste a text and then choose a character on specific line and place?. The above thing isn't that important. I just want to place a character on a specific line and place.
I mean something like this:
Enter a character:
You choosed " / "
On which line do want the character?
You choosed "Line 1 and 2"
Where do you want the the to appear on the line? (left or right)
You choose left.
Results:
Line 1. / hello
Line 2. / hello
I'm expected to write a c program for this question :

Question : Write a program that will prompt the user to enter an integer value and a character code to indicate whether they want to do a Kilogram to Pounds conversion (A) or a Pounds to Kilogram (B) conversion. Note that 1 kg = 2.2 pounds. The program should then do the necessary conversion indicated by the code and display the newly converted value to the screen.
Create a program that will ask the users name, age, and reddit username. have it tell them the information back, in the format: your name is (blank), you are (blank) years old, and your username is (blank).
So I started making my program
#include <stdio.h>
int main(int argc, char* argv[]) {
char name;
int age;
char username;
printf("Please input your name,your age,and reddit username");
scanf(" %c %d %c", &name, &age, &username);
printf(" %c %d %c", name, age, username);
return 0;
}
My program outputted H 0 and an upside down question mark. I was thinking that maybe the error in the program was that i was supposed to use %s instead of %c but im not entirely too sure.
I'm working my way through some C exercises to get some practice and have hit a wall. I need to use a function to take a number, such as 1, and print out One.Here's what I've got so far:
Code:
#include <stdio.h>
int name(int n);
char numberOne[] = "One";
int main(void)
{
int n;
}
[code]...
However, when I run the code and enter "1" the only thing that gets printed to the screen is "(lldb)". I've tried changing it to doing it without variables and just printing "One" but that gave the exact same result.
Write a C program that accepts 8 user input ratings on a new game. Print the lowest and highest ratings received. Use functions.
When i put in values to test the data it's not replacing highest or lowest it's just saying "The highest is 0.0" "The lowest is 0.0"
[#include <stdio.h>
double LowestAndHighest (double num);
void main(){
double num;
double RatingReceived =LowestAndHighest(num);
printf ("%lf", RatingReceived);

Directions:Write a program that reads an integer n from the user.
Display the first 100 numbers, with newlines every n numbers, using % operator

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

View 5 Replies View RelatedI have to optimize a code for below scenario. I am reading stdin (a file redirected to stdin) character by character. How many chars are going to come is not known. After every few chars there is a seaparator. e.g $ as below

While reading, if the separator arrives I'm processing the string stored before that separator and then continue reading stdin in same fashion, till EOF. I am using getc(stdin) to read chars.
Using gprof I can see most of the program time is spent inside main() , for this reading logic. Rest of the program is just some insert and search operations. I am getting time of 0.01 secs at the moment, want to reduce further.

I'm learning programming, and C++. I've got a question, but I couldn't solve my problem so far. I need to use arrays and only basic stuff to solve this:
Create a program that reads a word from the user and then print (cout) this word on contrary. It's simple, I know, but I can't do it,. I've tried some stuff but I don't get how I will get the proper values to do this. All I know is that I can use variable.lenght().
In my program, I'm supposed to read a text file (the name of which is given to me as a command line paramater, as long with an integer), and display the text in a specific format (each line can only be as long as the integer). However, I'm having trouble even reading the text file. I don't know the syntax. I'm only allowed to edit the function that does the formatting, and the code in that is
void typeset (int maxWidth, istream& documentIn)
I don't know how to 'read' the file, as most examples online are ifstream, or openFile or something like that. What I want to do is just read the first character of the file, and continuously keep reading characters until the end of the file.
So I'm trying to create a function that replaces any instance of a character in a string with another. So first I tried the replace() string member function:
In my implementation file
void NewString::ReplaceChar(const char& target,const char& entry)
{
this->replace(this->begin(),this->end(), target, entry);
};
Main program
#include "NewString.h"
using namespace ...;
int main()
[Code].....
Instead of replacing the the l's with y's it outputted a long string of y's. Also, NewString is derived from the string class (it's for the assignment). the header and whole implementation file, already tested.
I've also tried, instead, to use a for loop in ReplaceChar() but I need to overload the == operator and I don't know how I should exactly:
bool NewString::operator ==(const char& target)const {
if(*this == target)
return true;
[Code]....
I want the == operator to test if the value in the char array is equal to target but I'm not sure how to pass in the position. I'm guessing the this pointer in ReplaceChar() is not the same as the one dereferenced in ==() because target is never replaced by entry in the string.
Can we do this :
Code:
char strings[][100]={"ABC","EFG","IJK","LKM"};
char temp[100];
temp=strings[1];
I am making a program where the user enters numbers into an array and then a number,x. The array is sorted, then x is inserted into the appropriate place. I wrote my selection sort
Code:
void Sort(int ary[], int size)
{
int temp;
int smallest;
int current;
int move;
}
[code]....
put it wont print the numbers sorted when I use my print function, just the unsorted numbers.
is there a to use printf to print certain number of blank spaces, where the number is derived from the output of a function?
for(m=low; m<=high;m++)
{
printf("t=%2d %'f(m)-1's %3c", m, ' ',*);
}
This is suppose to output
t=-3 *
t=-2 *
t=-1
