conversion of Int to Char

chaitanya22

Actually, am having an array of Int values, i would like to convert into char array, as i need to save this data in a text file. am using itoa(), but i couldne get the result. Can anybody could help me out?

I suppose you want to convert int values into strings (and not into a char value). What is the problem with itoa ? You could also use sprintf.

Hi chaitanya22, For save data in the file please studing CArchive

You cannot convert the entire array at once using itoa. You have to pick out individual elements for conversion. For eg:

#include "stdafx.h"
#include "sstream"

int main()
{
string strIntArray;
stringstream sstr;
int randomArray[10];

     //fill this array with random elements....
for(int index=0;index<10;index++)
{
	randomArray\[index\] = rand()%10000;
}
     //convert each element...
for(int index=0;index<10;index++)
{
	sstr<

actually, i would like to load the int array data which is obtained from a machine to a txt file, i could open the text file, but i couldnt write the data i,e int array to text file, its writing some junk values. int array[100];//am having an int array char txt[100];//would like to convert the numbers in int array to string and should be stored in txt array. for(i=0;i<=100;i++) {itoa(array[i],txt,10); fwrite(txt,1,strlen(txt),f);//f=fopen("data.txt", "w+"); }

There is no need to convert just to save to a text file. Numbers can be written to the file just like characters can.

Hi Chaitanya, Try out this. FILE *fp; fp = fopen("chat.txt","w"); int a[10] = {5,15,25,35,45,55,65,75,85,95}; char p[20]; for (int i = 0;i < 10; i++) { itoa(a[i],p,10); fprintf(fp,"%s ",p); } Chetan. Helping others satisfies you...
