C :: Program Where User Inputs A String And Prints Out Length Of String
Jan 29, 2014
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?
In this code, i declared a string constant and trying to print the length of string. I know that if i write char a1[7] or char a1[] than it runs and give aggregate output, but in this case it is giving double length of string.
The print statement below I commented prints out unusual characters. I have two strings from the command line that I pass to the TKCreate function. Inside the function the strings print out fine, but when I return a pointer to the struct back to the main method one of the strings prints out fine, but the other one prints out unusual inconsistent characters.
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 = '.';
So we have a weekend assignment that is "Write a c++ program that will allow a user to input their first name into a string, and use the switch/case statement to produce the following output. Your Program should prompt the use rwith the numbers and the options for each (school, classification, and mood) allowing them to make a choice"
My issue is with the output. The output at the end is the number that they input and not the name of the case they chose, so if they chose option 1 for school it does not print out "BRCC" at the end for the output it prints a 1.
#include <iostream> #include <string> using namespace std; int main(void) { string name; cout << "Please enter your name: "; cin >> name;
How to make an input with a string thats part of an if statement. How I think it should be done :
#include <iostream> #include <string> using namespace std; int main() { string choose;
[Code] .....
But I get a strange warning (not an error, but something that is like "just letting you know" i suppose) and when i enter in ss or SS or aa or AA, it breaks my app.
I'm trying some codes about string arrays and taking array length. But i have some problems. I can't get length of string and can't send to a function.
------------------------ #include<iostream> #include<cstring> #include<string> using namespace std; void GetLength(string); std::string Words[]={"table","gun","programming"}; int main() {std::string InputWord;
I have problem with string compare. I want to compare the string user input with a string in binary. And I don't know how to do it. Problem in function login();Here is the code: And you also can download file in attachment too..
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 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?
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.
Code: #include<stdio.h>#include<stdlib.h> #include<time.h> #include<string.h> int main() { int found;
I can't find any method of retrieving the length of an array except for doing this:
string first[] = {"a","be","see"}; int length = sizeof(first)/sizeof(first[0])
This is a very unconventional way of getting the length of an array.
first->length() would return 1 because it returns the number of letters in the first element of the array (which actually makes no logical sense).
first.size() would return 1 aswell as it's practically the same thing.
Since getting the length of an array is such a fundamental feat, how come I can't find a decent method of doing it? Is there no buildt in method for this? If there is not, why has it not been implemented in the std?
The input consists of one or more packets followed by a line containing only # that signals the end of the input. Each packet is on a line by itself, does not begin or end with a space, and contains from 1 to 255 characters.
printf(" Enter a line of Morse Code for decrypting"); scanf("%s",phr); len=strlen(phr); for(a=0;a<36;a++) { if(strcmp(phr, morse[a])==0) printf("%c", alpha[a]); };printf(" ");
The output :
[output] Enter line to encrypt: ..... -.... --...
converting... 5 [/output]
It should read all code, including null. between coded letter one space, between coded word three spaces.
Write a program using user-defined function which is passed a string and that function should cycle the string.(Do not use any string related functions). E.g.
If the string is : Chetna then it should print as Chetna, hetnaC, etnaCh, tnaChe,naChet, aChetn
