I would like to understand a function on strings. Below is a code that I took from my teacher where the user inputs a string and prints out the length of the string.
Code: #include <stdio.h> #include <string.h> int main() { char str[100]; int i = 0;
[Code] ....
Now I understand that it returns the count in "int" so my question is:
Let's say i declared
Code: int count = 0; at the beginning of the code and then made Code: count = strlen(str); why wouldn't i have the same result? Is there a way to do it also?
I have a program that makes change from an amount. It works fine, but the output is the correct output looped over and over. I have tried everything, but it still doesn't work. For example, a amount of 98 should print
I have a program where the user inputs a line of integers, and then all unique ones are outputted. It works fine-almost. It prints the numbers correctly, but prints them more than once and I'm not sure why.
Code: #include <iostream> using namespace std; int main ( ) {
I need to make a program that prints certain pictures. My program compiles successfully. However, I cannot figure out how to view the ppm output. When i run the program i get a lot of random text.
I'm making a program that prints a triangle of @ signs given rows (but not columns).
For example, the output with rows = 4 would be: @@@@ @@@ @@ @
and rows = 3 would be: @@@ @@ @
However, trying to make this has given me a program that does something similar (but not the same):
for example, with my current program rows = 4 outputs: @@@@ @@@ @@ @
and rows = 3 gives @@@ @@ @
It seems that it's just missing a space (and therefore a setw and setfill), but I found 2 problems:
1. The space needs to not apply to the first line. 2. I can't get it to make a space before each row without making a space between each column.
My current code is:
#include <iostream> #include <iomanip> using namespace std; int main ( ) { int rows;
[Code] ....
I have tried putting in << setws and << setfills of various values but it seems to always apply to between each column as well as at the start of each row- what do I do?
[code]#include <iostream> #include <time.h> using namespace std;
int main() { srand(time(NULL));
[Code] .....
I am getting these errors when i compile it
random.cpp: In function âint main()â: random.cpp:23: error: expected â,â or â;â before numeric constant random.cpp:24: error: âRâ was not declared in this scope random.cpp:25: error: âRâ was not declared in this scope random.cpp:26: error: âRâ was not declared in this scope random.cpp:27: error: âRâ was not declared in this scope random.cpp:28: error: âRâ was not declared in this scope
So I need to make a program that reads distance and number of days of a person that is buying a ticket. If distance is greater than 1,000 kilometers AND the person stays more than 7 days, the discount is 30% of the ticket. The cost per kilometer is $1300. Print the ticket with discount.
I used variable distance as float because it will be multiplied with 0.3 for the discount... not sure if I'm right on that.
Code: #include <iostream> #include <conio.h> using namespace std; int main() { float distance; int days;
[Code] .....
I tried another way but haven't done it in code...
ask for distance ask for days
Ticket= (Dist x 2 x $1300) If (dist>1000) && (days>7)
So I need to make a program that prints a triangle of symbols in a certain direction.
For example: Code: How many rows? 3
@ @@@ @@@@@
How to do that. It's rare that I post without figuring anything out, but I'm just simply not sure. I have a program that prints a triangle in a similar direction, so maybe if I could get some hints as to what to do with that (HINTS, not direct source code) .
Code: #include <iostream> #include <iomanip> using namespace std; int main ( ) {
I am working on an assignment to enter a number and print all the prime factors of that number. I have that working, but the assignment demands the output be formatted in a strange way which I can't figure out. For example, in my current program entering 10 gets me 25, which is actually 2 and 5. But it should get me: ( 2 * 5 ) but I can't figure out how to do this. On the chance you need it, my code is below:
Code:
#include <iostream> using namespace std; int main( ) { cout << "Number: ";
Write a program that prints a multiplication table using nested loops. In main ask the user for the smallest column number , the largest column number and the size of the increment. Ask the user for the same information for the row values.
In the example the column values entered are: 5, 15 and 2 and the row values 3, 6 and 1.
Given those numbers you would generate the following table.
Multiplication Table | 5 7 9 11 13 15 ___|___________________________________ | 3 | 15 21 27 33 39 45 4 | 20 28 36 44 52 60 5 | 25 35 45 55 65 75 6 | 30 42 54 66 78 90 Print the 24 values with the grey background. The other numbers show the values to be multiplied.
Code: #include<stdio.h> main() { int a,b,c,d,e,f; int i,j,total; printf("Please enter smallest column number: "); scanf("%i",&a); printf("
[Code] ....
Challenge: As an added challenge try to print out the column headings (5 7 9 11 13 15) and the row headings (3 4 5 6)
I'm trying to create a program that prints a number of dots specified by the user, there 4 options to do any loop type or to exit the menu. i'm having problems making it so that after you enter a value and it displays the specified number of dots it clears the results. Also we have to make it so that if a negative integer is entered it still prints out the appropriate amount of dots ie: user puts -9 it prints 9 dots, i know you use the abs() function but it doesn't seem to be working for me. I'm assuming my problem with the abs function is i'm not using it correctly. Use case 1 as the example for the rest because I'm trying to implement everything on one case at a time
Code:
int main() { //initialization statements int Num1 = 0; char dot = '.';
the question is; Write a program that prints out the memory addresses of each element in a two-dimensional array. Check to see if the values printed out make sense to you based on the way I explained it before.
Below is the code I have done. I am having problems printing the "-" sign to keep formatting with the board when the user enter in different dimensions other than [4][4].
Code:
#include <iostream> using namespace std; void printTable (int x, int y) { int **p_p_twoDimension = new int* [y]; for (int i = 0; i < y; i++) { p_p_twoDimension[i] = new int [x];}
I'm trying to parallelize bottom's up merge sort algorithm. Firstly, i must have working procedural code.
I rember I had my code working last week but I made some changes ( probably to arguments passed to sort function ), i run my program several times without rebuilding it so i though it's still working.
Now i came back to my code and my program terminates without any message which confuses me. I debbuged merge function and it seems to work well, at the end i have sorted array.
I'm just getting back into the swing of things after a long time of not programming. I'm trying to create a program which takes in command line arguments and prints the last one. My code is as follows:
#include <iostream> #include <vector> #include <string> using namespace std; int main() { string x; vector<string> arguments;
[Code]...
And the error message I receive, a simple but frustrating one, is as follows:
Enter arguments, enter STOP to stop: Segmentation fault...
I need to create a program that prints a certain number of asterisks based on user input. The user inputs 5 and I want my program to output "*****". How would I do this in C? I've tried printf("%#**", myvariable) but this does not work it only prints "*".
I want to be able to type a message into another program (such as notepad) using C++. How would I do that? Is there a function to do this, or an event, or something?
A program that asks 10 positive integers and classify them as odd or even positive integer inputs. The algorithm has to trap negative integer inputs. The output will be displayed in two columns. ODD and EVEN.
here's my program code...
#include<iostream> using namespace std; main() { int countA;
I want to create a grading program that the user inputs a name and then on that value (name) there is a vector of doubles to represent his/her mark and then calculates an average how would I go about doing this?
I've search the web, and solved all the errors that appeared till I got a clean build. Now any time I run the code I run into this issue.
enter hour of mtime : 19 Mmin: 26 Msec: 05 standard time is 12:00:00 AM military time is 00:00:00
I can't figure out why this isn't displaying any of my inputs.
#ifndef TIME_H #define TIME_H class Time { public: Time(int = 0, int = 0, int = 0); ~Time(); int hour; // valid values are 0 to 23 int minute; // valid values are 0 to 59
