I'm new to C and was wondering if it was possible to print multiple characters to the same file using the fprintf function provided in one of the C standard libraries?
View 1 Repliesso 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]);
[Code]...
Its my 1st time using fopen,fprintf and others and i cant seem to edit my file via fprintf! Heres my program:
Code:
#include <stdio.h>
#include <stdlib.h>
char letter,check,nought,bleh,hi,a;
int main()
[Code]....
Code:
struct sth {
char* str;
} pt;
}
[code]...
fprintf does not save string to file. How can I put structure into list?
I am trying to take text from a file and have it displayed using fprintf at line 46. When I run the below code nothing prints out. My text file has 4 lines with 5 different strings separated by whitespace.
#include <cstdlib>
#include <vector>
#include <cstring>
#include <stdlib.h>
#include <errno.h>
#include <stdio.h>
using namespace std;
//declare my own struct

I have written a C++ program I have multiple of CSV file used as input, which I open one at a time and close it after extracting data to a output file which is the only file.
I run getline(inFile,line);
outFile << line << endl;
I run this code, and only part of it is goes to the output file I got, also have spacing randomly to specific file and inconsistent
But when I slower the code, like system("Pause") in the loop, I can get extract what I want perfectly....
Is my program running to fast, why getline would be skipping part of what things I want?
I cant print the characters in the end.
Code:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int main()
{
FILE *arquivo1,*arquivo2,*arquivo3;//files i will open//
char texto;//texto= character i will read.
[Code]...
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 supposed to compare 2 strings and print out a 1 if the characters match and a 0 if they dont. It compiles but doesnt give me the correct output.
Code:
#include <stdio.h>
#include <string.h>
void func();
int main () {
func();
return 0;
[Code] ....
#include<iostream>
#include<conio.h>
using namespace std;
int main(void){
clrscr();

I am trying to print ascii characters but problem is If i put a limit in for loop to 255 or more than 126 the output don't stop it keeps on going
I know there is another way to this program but what i want to know this why this happen in this logic....it doesn't happen if a<=125 or less then 125.
I am quite new to C programming. Now facing lots of problem with the code below. I attempt to convert he alphabet sorting into function prototype model but still facing warning during compilation.
Besides, I wish to open multiple file at the same time as well using array looping method, but got no idea to modify it...

Code:
#include <stdio.h>
#include <string.h>
#define SIZE 255
#define LEN 31
// Function prototype
void alphabetisation (int final, char *webaddress[]);

Q1. Recursive function that receives an integer x and prints the alternating alphabetic characters.
Write a main function to test the function;
ENTER NUMBER : 4
A C E G
Q2. Define a void function that finds the smallest value in the array and number of its occurrences. Also, it finds the largest value in the array and number of its occurrences.
ENTER 4 NUMBERS:
1 12 5 41 41
THE BIGGEST IS 41 AND IT OCCURS 2 TIME
THE SMALLEST IS 1 AND IT OCCURS 1 TIME
I declared all functions in header file, such as:
bool readCase();
bool meshing();
bool readMesh();
bool calculateFlowfield();
bool readFlowfield();
bool calculateEvaporation();
And then I define them in separated .cpp files, each .cpp file include the header, but I got multiple definition error, why?
Even the int main() function, which only decalred and defined once got this error, why?
Is it possible to apply Print Conversion Specifiers to a single value multiple .
simply put ,
printf("%.1s%6lf

I want one digit precision and 7 tab space on this item.
i have two variables which are arrays and want them to be written below the other once all the values of one variable is written . how can i do that using fprintf function in c++ ?
View 1 Replies View RelatedI have the following piece of code which should write the contents of my vetor to y file but I am getting a very weird output in my file.

As you can see this doesn't make sene because the file should also contain the exact same things as the cmd outputs. What's going on here ?
I am making a program where the user enters numbers into an array and then a number,x. The array is sorted, then x is inserted into the appropriate place. I wrote my selection sort
Code:
void Sort(int ary[], int size)
{
int temp;
int smallest;
int current;
int move;
}
[code]....
put it wont print the numbers sorted when I use my print function, just the unsorted numbers.
I have this error - [Error] 'fprintf' was not declared in this scope (line 32)
and this - [Error] 'fclose' was not declared in this scope (line 33)

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!
View 6 Replies View RelatedI wrote a function to count the number of characters in a string. Curious as to why I have to return x-1 and why x isn't the number of characters.
Code:
int count(char *string){
55 int x = 0;
56 char *p;
57 p = string;
58

this code asks the user to input words/strings until he enters "end."after that, the program must copy the input to a text file named read.txt...I entered 'j' and then 'end' and after that I looked at the read.txt file and here's what's in it.
Output:
Code:
j
; end
some weird characters appeared!! the characters in the text file should only be.
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,

To generate output data, I'm printing a bunch of vector contents to files. Because the type of variable can differ between vectors, I wrote a templated printing function to print out whatever the content of the vector is. It looks like this:
template <class T>
void SomeClass::PrintVector(std::vector<T>& Values, std::string& outFile) {
std::ofstream out(outFile, std::ios::app);
[Code] ....
I added the fixed because some larger values were being printed in scientific notation. Everything works well. My test code includes 3 vectors of doubles and 3 vectors of unsigneds. All the unsigneds work well and two of the doubles work well, but the third doubles vector prints nonsense unless I disable the fixed.
The calling code is the exact same. I know the values in the vector are correct, because a) if I comment out the "fixed" flag it works, and b) one of the unsigned vectors is sorted based on the values in that double vector (after it is printed, so the sort cannot corrupt the vector print) and works perfectly.
The "nonsense" looks like chinese/weird characters, if that matters.
I have a big problem with a function, I wrote this function in order to get a line from an HTML (Or XML) file, until a specified delimiter (not always or
... It can be everything..)
Here is my code :
public static String GetLineUntilChar( String url , char delimiter , String postData, String referer, String cookie ) {
try {
Uri uri = new Uri("http://127.0.0.1//site.html");
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri);
request.ContentType = "application/x-www-form-urlencoded";
if (!String.IsNullOrEmpty(referer))
request.Referer = referer;

I am attempting to write a recursive function that, given a string, recursively computes a new string where all the lowercase 'x' chars have been moved to the end of the string.
For example,
moveXs("xxre") --> "rexx"
moveXs("xxhixx") --> "hixxxx"
moveXs("xhixhix") --> "hihixxx"
Below is the code I have written thus far, but it seems to be returning only empty strings.
string moveXs(const string& str) {
string strCopy = str;
if (strCopy.length() <= 1) {
return str;

I'm using the Visual C++ Express 2008 and i need to pass as parameters to a function characters coded in UTF 8. My environment is Windows 7. The editor of the VC++ write in UTF 8 or UTF 16? If it writes in UTF 16 how can i change it?
