I have an array of characters. I am trying to find "houston". The only way I can think of to do this is to use a for loop and check each individual character. Is there an easier way to do this?
char string[] = "Fishing tourism miami atlanta dallas houston";
so my question is i want to print characters,no string just an array of characters,i do this but it s not working,maybe i have to put the '' at the end?
Code:
int main() {
int i;
char ch[5];
for(i = 0; i < 5; i++) {
scanf("%c",&ch[i]);

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 am trying to write a function compress() that takes in an input of a 2-dimensional array (5x10) of character data, compresses each row of the array by replacing each run of character with a single character and the number of times it occurs, and prints on each line the result of compression in the function. For example, the row with data aabbcdddee may be compressed into a2b2c1d3e2.
Input (5x10 of characters):
aaacccdeee
sssseeeedd
aaaaaaaccc
eeedddasee
ddeeeeeggg
Output:
a3c3d1e3
s4e4d2
a7c3
e3d3a1s1e2
d2e5g3
I could achieve the compression part, but behind the compressed array, it printed out 5 extra lines of alien ASCI code, followed by printing out 5 times of everything .
Code:
void compress(char data[SIZE1][SIZE2])
{
int i,j, k,l ,count;
char data123;
printf("Enter your data (5x10 of characters): ");
for (i=0; i < SIZE1; i++) {
for (j=0; j < SIZE2; j++)
data[i][j] = getchar();
fflush(stdin);
}

I have written this program to copy all the characters input from the keyboard into the array till a "?" mark is entered. what is the error i am doing. I am getting a run time error in this case.
Code:
void word_reversal(void) {
char array[100];
int index=0;
printf("Enter the number of characters less than 100
");
do {
scanf("%c",&array[index++]);
}while(array[index] != '?');
}
I have tried to search all about strings,I have the occurrences and have worked out what letter corresponds with which. I have searched that much i can remove the vowels and reverse my string but I dont know how to swap them. This is what i have this far. When it compiles it just prints the decipher is:
If i even find out am i on the right track ive used caps when swapping to try and stop the doubles over writing,...

Here's the question: Create a program that accepts an array of characters. And displays the converted array of characters into Upper case if it is given in Lowercase and vice versa. Don't use string, but char.
Example: mychar ="I am A conQUeror."
Code: //My Codes:
#include <iostream>
#include <conio.h>
using namespace std;
int main()

my question is located as a comment beside the last printf ! ? check the comment near the last printf the comment is ==>here i get a sequence of numbers the question is how can i copy this sequence to an array and the print the array out ?
Code:
#include <stdio.h>
#define N 30
#define n 100
[Code]....
here i get a sequence of numbers the question is how can i copy this sequence to an array and the print the array out ?
Code:
#include <stdio.h>
#include <string.h>
#include <conio.h>
#include <math.h>
void reverseAr(char ar[], int n);
int main() {
int choice;
char *abc= ar[];

My codes keep couldn't get the reverse array of characters.
I am trying to learn how to declare a pointer to an array of characters. And here is the code i have written. But iam getting a warning saying assignment from incompatible pointer type p = s.
Code:
#include <stdio.h>
int main(int argc, char *argv[]) {
char (*p)[10]; // pointer to an array of 10chars
char s[10] = "Hello"
p = s;
printf("%s",p);
return 0;
}
I have initialized a multidimensional array eg char fruit[5][10]...Then I would need to read in 3 words with spaces in between from user and store in fruit[5][10] e.g "pear apple orange"
The thing is that after typing orange, when I press Enter it still prompts me to enter more characters. How can I end the scanning of characters after orange ?
I am developing a program which should multiply two character arrays of length of 40 treating as signed numbers for example:
char arr[4] = {'-', '1','2',' '}; is equivalent to -123 in integer form.
now i have this in 40 size of array and i have two arrays . What will be the algorithm that should i employ? i can't find the way to implement this.
Same goes for Division, +1 what about 40bit numbers division.
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 .
Assume you want to use a loop to process an array of characters starting from the beginning of the array. You want the loop to stop when you read the null terminator character from the array. Fill in the loop test condition that will make this work correctly.
index = 0;
ch = array[index];
while ( _____________________________)
{
// process the character
index++;
ch = array[index];
}
I have been looking everywhere, but the only place I have seen it done is Objective C. The Question: how do I split a string, input by the user, into an array of characters? No code shown because I know no commands that do this.
--Input by user as in fgets, or scanf().
Eg. User input : abcde
Program Output : edcba
I keep on getting weird ASCI symbol in return, I couldn't achieve what I need, and tried debugging for days,
Code: char ar[20];
int len,n=0;
printf("enter the string to be reversed :

My question is how create a function to remove all vowels defined as characters('a' 'e', 'i', 'o', and 'u') from the array provided to it.
An example of how the function should work:
input: Hello world, how are you?
output: Hll wrld, hw r y?
Code:
int removeVowels(char arr[]) {
int i;
//move through each element of the array
for(i = j; arr[i] != '/0'; i++) {
//if the last character was a vowel replace with the current
//character
[Code] .....
Below is an extracted portion of an example exercise from the C Programming Language book:
Code:
void escape(char * s, char * t) {
int i, j;
i = j = 0;
while ( t[i] ) {
switch( t[i] ) {
[Code] ....
Here's my problem with this. s is a pointer to a char array. That means each index stores 1 byte. A backslash character '' is one byte. In above example, we escape it with a second backslash character: ''. That means we have two bytes there. So why does it allow inserting two bytes into a one byte index?
I am trying to store the HTML codes for different characters in an array, but I am not sure how to do this, so that when using the keybd_event it can be plugged in.
If you try to do it with a string for storing the HTML code, you get this error.
string HTML[1];
HTML[0] = "A"; //A
keybd_event(HTML[0], 0, 0, 0);
I could do it in a very long if/else statement, but this would be much easier to call and get data from, and take up less space.
Basically I am making a console RPG (isn't every beginner nowadays?) and I am having an incredible amount of trouble assigning specific characters their own color. e.g. monsters being red, cash being green, etc.
I took out Left, Right, and Down controls because of character constraint.
#include <iostream>
#include <windows.h>
//%%%%%%%%%%%%%% COLOR CALL %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
void setcolor(unsigned short color) {
HANDLE hcon = GetStdHandle(STD_OUTPUT_HANDLE);
SetConsoleTextAttribute(hcon,color);

I have been working on a project that deals with an array of characters and finding there frequencies. I was able to determine the frequencies that where greater than 1, but I need to find the HIGHEST frequency.
Here is my full code:
#include <iostream>
using namespace std;
void input(char unlisted[80], int& n);
void bubblesort(char unlisted[80], char sortedlist[80], int n);
[Code].....
As you can see this will print out all frequencies that are bigger than 1, but I only want the highest frequency. Basically I want to print out all frequencies when count is greater than 1 less than count, but because its in a loop count will always be greater than count-1 so it prints out all frequencies.
I am trying to generate possible combinations of 4 lower case letters from aaaa - zzzz. The words will then be used against a file that contains encrypted passwords that each relate to a 4 lower case word. I have successfully generated the words. Now all i need to do is put the created words (aaaa, aaab, etc...) to an array so I can use crypt((array[i+1]), buff) and print the encrypted 4 letters that come from the file. I am having a lot of trouble complete this though.
New problems that are occurring
The main problem is in the all function and main. I'm not wanting to print the aaaa, aaab, aaac, etc to the screen but I want to put it in an char array so that i can compare each individually to each line from the file using crypt. How to put all 456976 combinations into an array, compare it to each line of code, and print the solutions to the screen.

In Unix (HP-UX) and Linux, the output of above program will be:
t.a=Helloworld!
Instead of the value of t.a ,i.e, "Hello" only.
Why such output? And what is the trick here to print the only value of t.a.
I am wonder what is the fastest way of changing elements in array of characters for encode purpose, here is simple example presenting an idea:
Code:
char *a = "123456789":
char b[] = "ABCDEFGHI";
int 1;
for (i=0;i<strlen(a);i++) {
b[i] = a[i];
}
Is this approach better or worse than bit manipulation ?
This code work perfectly, as follows.
Code #A:
#include <iostream>
#include <cstring>
#include <vector>
using namespace std;
typedef std::vector <void *> gr_vector_void_star;
gr_vector_void_star output_items;
[Code] .....
Output of above code #A:
char * sentence = "Angel";
for (int i=0; i < 5; i++)
{ out[i] = sentence[i]; } // error: invalid conversion from 'char' to 'char*' [-fpermissive]
It fails to compile with error message "invalid conversion from 'char' to 'char*'".
So the plan is to create a word search by reading in characters from a file into an array. This is my code so far, nowhere near finished but have encountered a problem already:
Code:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#define ROWS 20
#define COLUMNS 20
int main()
{
[Code]...
My question is to do with the section highlighted in red... I can't really see why it is not printing out my array (wordsearch), it's probably very basic but I have no C experience so am not too confident in what I'm doing.
