C/C++ :: String Prints Unusual Characters?
Sep 10, 2014
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.
#include <stdio.h>
#include <stddef.h>
#include <stdlib.h>
#include <string.h>

I'm doing an exercise that prints all input lines that are longer than 80 characters. I rather not use any libraries so I decided to write my own function that counts characters to use it in my main program. However when integrate things my function returns zero all the time.
Here is my full code:
/* Exercise 1-17 Write a program to print all input lines that are longer than 80 characters */
#include<stdio.h>
/* Declarations*/
#define MAX_STRING_LEN 1000
int count_characters(char S1[]);
int main() {
[Code] .....
So I was trying to debug my count_characters() function and this is the code if I was to run it seperately:
Code:
#include <stdio.h>
/* counts character of a string*/
main() {
int nc = 0;
int c;
for (nc = 0; (c = getchar()) != '
'; ++nc);
printf("Number of characters = %d
", nc);
}
which works...

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?

Im supposed to find the common characters between two string characters, assuming that the user wont input duplicate letters like ddog. When I run my code I get an output of a question mark upside down. Here is my code with comments on what each part is supposed to do
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int main(){
char str1[20], str2[20],remp = ' ';
int size1,i,j,temp;
printf ("Input the first string");

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
3 quarters
2 dimes
0 nickles
3 pennies
but instead it prints
3 quarters
2 dimes
0 nickels
3 pennies
0 quarters
2 dimes
0 nickels
3 pennies
0 quarters
2 dimes
0 nickels
3 pennies
Why it's doing this?
Code:
#include <iostream>
using namespace std;
int coinscount(int& amount, int value) {
int tracker = 0;
int amountdimes = amount;

I am stuck in this program, Be given a string of chars, where each single char belongs to the following alphabet: a..zA..Z0..9 (So, in the string there are only lowercases, uppercases and digits. No blank, no comma, ...). For every char of the given alphabet, count how many times in the string
1-- the char belong to a sequence of identical chars whose length is at least three (i.e.: in the string cc74uyrpfccc348fhsjcccc3848djccccc484jd for three times the character 'c' satisfies this condition)
Code:
#include<stdio.h>
#include<conio.h>
#include<string.h>
[Code]...
2-what is the longest substring of characters strictly rising interm of ASCII code(the following is greater (>) of the previous)
3- what is the longest substring of successive characters interm of given string rannge (i.e.: fhkjshdfruytyzABCDEfglsj => 7)

i have a string which is n characters long. i need to read say 20 characters at a time, wait for the user to type OK and then send another 20 characters. wait for the user to type OK and send 20 characters again until we get to the nth character.

I want to remove a particular character from a string. Say '.'. I've tried the following:
void removeDots(std::string &x)
{
std::remove_if(x.begin(),x.end(),[](char c){return (c == '.');});
}
This has the effect of removing the dots but keeping the length of the string the same, so old characters are left over at the end. Is there an extra action to do to x to make it the right size or is there a better way of doing it?

I'm working on a programming challenge and i need to uppercase all characters of the string.
string upperCaseIt(string& name){
for(int index = 0; index < name.length(); index++){
name[index] = toupper(name[index]);
return name;
}
}
My problem is that it only uppercase the first character of the string.

Iam working with arrays and i cant get to the write solution to cout the characters.
the Question is : Write a program that inputs a character string from the user as an input (using cin.get())and store it in myStr[ ] array.Assume that the length of the input string is less than 100 characters and the string may contain lower case, upper case, and/or symbols.The program should then print the number of lower case, upper case, digits, and symbols along with the characters themselves.
my code :
#include <iostream>
#include <string>
#include<iomanip>
using namespace std;
int main() {
int ctr1=0, ctr2=0, i=0, ctr3=0;
[Code] ...
What i have now, how can i cout the uppercase characters and the lower case characters and the symbol characters !

I am trying to cout just the first 5 characters the user enters into a string. I'm not sure how I can discard or not show the rest of the characters they try to enter after 5.
#include <iostream>
#include <string>
using namespace std;
int main() {
string random;
cout << "Enter any word." << endl;
cin >> random;
cout << random; //want to ignore everything after first 5 characters entered.
return 0;
}

1. The debugger shows that the characters are entered into the word pointer, and when a punctuation or space character is encountered, I terminate the string with a ''. But when I use puts to print the string, garbage is printed. Why is this?
2. Also, if I don't allocate memory for word the compiler gives a warning about it being used uninitialised. But I didn't allocate memory for the array of pointers(words), and the compiler didn't give any warnings. Whats the difference between a pointer and an array of pointers?
Code:
// wordcount.c - count words.
#include <stdio.h>
#include <ctype.h>
#include <stdlib.h>

So I'm writing a function isPalindrome() that can accept a string as an argument, and copy from it only the alphabetic characters in the argument (original) string to another string named alpha_array which contains only the alphabetic characters. Then the function should be able to call the isPurePalindrome function to determine if alpha_array is an ordinary palindrome.
The problem is that when I call isPalindrome in main, the program crashes.
Here's the code I have for isPurePalindrome and isPalindrome:
Code:
/* 1 */
int isPurePalindrome( const char * sentence ) // Can accept strings, array and pointer arguments
{
// Declarations

I can not cope with the task.Create a function that will take a string of characters (including spaces) and print the numbers of characters (including commas, periods, etc.) in it. The output will be arranged alphabetically. Distinguish case sensitive!

is there any function to print a string with all the escape characters in it?
For example, instead of printing:
This is a string.
It would print:
This is a string.
Or in Windows:
This is a string.
I know that you can debug the code to find the variable contents, but is there any way to accomplish this with some standard library function?

This program is suppose to read a matrix file , and the first getline is suppose to get the file header but it appears that 'line' doesn't take in any value other than empty thus causing all the problem , I tried to put cin.getline() in front of it to take away the /n created by the cin before it , but it doesn't work . When I debug the program when the arrow points to the string line , this error appears
line<Error reading characters of string.>std::basic_string<char,std::char_traits<char>,std::allocator<char> >
I tried to initialize string line=NULL too , doesn't work either.

I have the following string array
string[] output= input.toArray();
each index has a set of two characters, for example:
output[0] has 'th', output[1] has 'is'
I want to take t and h and compare them or do anything with them, but it must be in pairs.
I tried foreach but I don't know if there is a way to compare the element with the next element .
