C/C++ :: Read Integers Into Array / Sort Numbers And Print Out Occurrence Of Each Number

Apr 6, 2014

My C programming class wants us to write a program to read integers into an array, sort the numbers and print out the occurrence of each number. I've tried everything that I can think of but the core dump is still occurring.

void countValues ( FILE *inf, int list[], int size ); /* Function prototypes. */
void printFrequencies( const int list[], int size );
int main (void) {
int status = EXIT_SUCCESS; /* defaulting status to success. */
FILE *inf = fopen( "numbers.txt", "r" ); /* input data file */

C++ :: How To Count Repeated Numbers In Array

Jan 30, 2015

So I already gave this a go and will post my code below. The question is about the last loop before the program cout's. i thought the count would keep track of the repeated numbers so i could display them but it does not. I italicized the loop i am referring to. or at least i tried to xD

#include <iostream>
#include <iomanip>
using namespace std;
int main() {
int inputs[30];
int numofloops;
int maxvalue = inputs[0];

C++ :: Counting Occurrence Of Char In Array

Aug 25, 2013

I have

#define LessSymbol -1
#define MoreSymbol 1
#define NeitherSymbol 0
#define MAX_COLS 20
#define MAX_ROWS 20
#define MAX_CHAR 3

char averageMap[MAX_ROWS][MAX_COLS];
char rowCount[MAX_ROWS][MAX_CHAR];
char colCount[MAX_COLS][MAX_CHAR];

I have other stuff in the code, but basicly, at this stage i have a map of 1's,-1's and 0's in a 20 x 20 map. I just want to count the occurrences of each and basicly tally them in the 3 colums/rows at the end of the bloc. so far ive tried many different if statements, here is what i tried last.

for(row = 0; row < MAX_ROWS; row++){
rowCount[row][0]=0;
rowCount[row][1]=0;
rowCount[row][2]=0;
} for(col = 0; col < MAX_COLS; col++){

[Code] ....

Its outputting 20 as a result for each row. Its like its counting the symbol no matter what it is.

Visual C++ :: Program That Count From 1 To 12 And Print Count And Its Square For Each Count

Dec 16, 2014

4.1 Write a program that will count from 1 to 12 and print the count, and its square, for each count.

4.2 Write a program that counts from 1 to 12 and prints the count and its inversion to 5 decimal places for each count. This will require a floating point number.

4.3 Write a program that will count from 1 to 100 and print only those values between 32 and 39, one to a line. Use the incrementing operator for this program.

C :: Calculate Prime Numbers In Range And Return Count Of Prime Numbers

Apr 28, 2013

I wrote a program which sends a starting and ending range to other processes and the processes calculate the prime numbers in that range and return the count of prime numbers to the head process, process 0. But this is not working properly at the moment. I realize I still have to split up the range based on how many processes I have...I still have not figured out how I want to set that up. I

Code:

#include <stdio.h>
#include <stdlib.h>
#include <mpi.h>
int isPrime(int num);
int main(int argc, char **argv){

C++ :: Count The Repeated Numbers?

Jul 12, 2013

I am using this code that to check a set of values from a text file and show it on the output.

Code: void MatchNumber(int b) {
vector<Rect> rects;
ifstream theFile("CheckNumber.txt");
double x1,y1,x2,y2;
while(theFile >> x1 >> y1 >> x2 >> y2 ){
rects.push_back(Rect(x1,y1, x2,y2));
}
int num=0;

[code]....

I want to calculate how many times the common number is repeated . So I have used freq[num] in that function. But I am getting the output like this-

Code:

The common number is = 5
The 5 repeated = 1 times
The common number is = 6
The 6 repeated = 1 times

The common number is = 4
The 4 repeated = 1 times

The common number is = 5
The 5 repeated = 1 times

[code]....

So the freq[num] is only returning 1 instead of counting the total number of repeating which is wrong!! I would like to have somthing like this in my output -

Code:

The common number is = 5
The common number is = 6
The common number is = 4
The common number is = 5
The common number is = 5
The common number is = 8
The common number is = 9
The common number is = 6
The common number is = 6

[code]....

How can I do that?

C++ :: Count The Numbers Below The Average

Mar 7, 2013

I have loaded and 1d array from a .dat file, calculated the average of all the numbers. Now I need to count every number in the array that is below the average and cout that number. This is the method in the class I have so far:

int IntegerArray::countBelowAverage(int numBelowAvg) {
avg=IntegerArray::getAvg();
for(int ct=0; ct<avg; ++ct) {
numBelowAvg=ct;
}
return numBelowAvg;
}

My output from this is always 0 and I know that there are numbers below the avg.

C/C++ :: Making String Count Numbers / Blanks And Alphabetical Characters

Sep 20, 2014

I'm trying to create a program that counts the amount of alphabetical characters, numbers, blanks and total amount of characters in a string a user gets to enter. The user also quits the program manually by pressing CTRL + D (in linux terminal).

These are the results I get from the code so far by typing in "hello cplusplus 123 c++" CTRL + D.

The string had:
Alphabetical characters...: 0
Numbers...................: 0
Blanks....................: 3
Total amount of characters: 20

So I can't seem to find a way to count the amount of alphabetical characters and numeric characters.

Here's my code:

#include <iostream>
#include <string>
#include <iomanip>
#include <cctype>
#include <sstream>
using namespace std;
int main() {
string tecken;

[Code] ....

The reason why I declared cctype is that I think I should use the isalpha, isdigit and isblank functions but how I am supposed to do that.

C++ :: How To Enable Array To Count Items From A Group

Dec 27, 2013

Arrays are by far the most fun to work with and I really need see if its possible to enable an array to count apples, pears, peaches, from a group of three each.

If any of the fruit groups were chosen how might an algorithm be put together to count how many were chosen from each group. But lets take into consideration that these fruit groups are not supposed to be randomly generated, instead they belong as an array with certain amount of chosen occurrences. To show how many fruits were chosen from each group example, 1 from group 1, 2 from group 2, 3 from group 3 the out put is the important part because it shows the group and the occurrence of that group. the algorithm should be able to display the group with an occurrence as well

C/C++ :: Calculating Letter Count From Array Of Pointers To Strings

Feb 28, 2015

I need to calculate how often each letter appears in a text file from a function that is called from main() with an array of pointers to char and how many pointers there are in the array. The code i have so far is:

#include<stdio.h>
#include<string.h>
#include<ctype.h>
#include<stdlib.h>

[Code]....

I get no errors and it runs but it gives me the wrong output. I know my array is correct because when i print it in main() it is correct but each letter is incorrectly counted. When i give it the input .txt file of:

This is one line of a string
This is another
This is the third one
Wow heres another one
It counts a as 8
b as 1
c as 3
etc.

I have hand traced it and cant figure out why it isnt giving me correct values

C++ :: Replace 2nd Occurrence Of Letter?

Apr 27, 2013

i`m currently racking my brains out over this issue. How do i go about the x as the first occurrence of the letter?

lets say helxo , x is the 2nd occurrence of l. I will want to change back x into l

i have replaced it with x in the earlier step with this code...

string everySecondChar(const string &s,char source,char distance)
{
string t(s);
for(std::string::size_type even =0,pos=t.find(source,0);pos!=std::string::npos;pos=t.find(source,++pos))
{

[Code]....

i would like to reverse the process now, letting x becoming l again!

C++ :: How To Replace 2nd Occurrence Of A Letter With X

Apr 21, 2013

Supposed i have a word hammer.

how am i suppose to search for the 2nd occurrence of the letter and then replace it with x?

example hammer will become hamxer

I thought about using replace for it, however i`m lost on how to find 2 occurrences of the same letter in the word.

string formatEncrypt(string message) {
int msgLength=message.length();
for(int i=0;i<msgLength;i++) {
if(message[i] == 'j' {
message[i]='i';

[Code] .....

at line 31 i tried to put a z into the alphabet that occurs twice.

this is what i have done so far

example: hello world

It will turn out as helzlo world

However i want to make the output appear as helzo world
