Thanks for reply Now i am getting exception in line
s[l]=0;Unhandled exception at 0x1026f8bc (msvcr90d.dll) in TestingProject.exe: 0xC0000005: Access violation reading location 0xcc006975.
try this
char *s = new char;

I all I got one example from planetsourcecode.When i compile these code then i am geeting error please help me.
#include "stdafx.h"
#include<stdlib.h>
#include<stdio.h>
#include<conio.h>
#include<string.h>int _tmain(int argc, _TCHAR* argv[])
{
char *s;
int i,l,*a,f,c,x;
printf("Enter a string : ");
scanf("%s",s);
l=strlen(s);
s[l]=0;
a=(char*)malloc(l);
for(i=0;i=l){ a\[x\]=c=0; if(x<0){f=0;break;} a\[x\]++; } } printf("Completed"); return 0;}
Error
error C2440: '=' : cannot convert from 'char *' to 'int *'
error C2109: subscript requires array or pointer type
error C2143: syntax error : missing ';' before ')'Please help me
You can use casting, I know it's available in C++. Don't know about C, does it have to be C or C++?

thank for make comment but sorry can you describe in detail.What's not available? please describe in detail.
i'm not sure if you've attempted to add float to an int data type, but you get compiler errors in the end. you want to add float and int to each other. Casting: int x = 12; float y = 4.0; int sum = x + (int)y;

no, no, no .... That's not the way to go! You put some code with some syntax error and even some misconception in it. That reveal that you are not understanding what your code has to do. The compiler just gives some errors, but those errors are random as your code is. Attempting to fix those errors doesn't lead anywhere: you're never granted your code will do what you expect. For example:
char \*s; int i,l,\*a,f,c,x; printf("Enter a string : "); scanf("%s",s);sis a pointer pointing to nowhere: where do ypu thoing your scanf can write to ?!?s[l]=0;tries to write to nowhere since s is nowhereais a pointer to int, but you doa=(char*)malloc(l): what did you want to do? allocating char-s or int-s ?!for(i=0;i
f=1,c=0;
while(f)This is a mess of tokens with no syntax meaning! Raed about the
forsyntax, and understand the proper use of '()', ',', and ';'.x=l-1Wow... you're looking for problems: never use names like "O" and "l": I have to change font before find it's "l-1" and not "l-l" ... Do you get what I mean? If not, than that demonstrate the problem :-) Then: I see amalloc, but i don't see afree: not a good way to program... I don't continue, but what can you do if you don't have clear in your mind what you're gonna do?2 bugs found. > recompile ... 65534 bugs found. :doh:

Thanks for vital information and suggestion. I want to generate Combination of given String.Like this CString test="ABC", then generate like this AB AC AA BB BC BA CC CA CB If you have any type solution or suggestion then please help me.
Ok, that's the problem. Now try to come to an algorithmic solution. That doesn't need to be C or C++, just pseudocode. Only when you find your algorithm looks meaningful, try to code it! Than: the problem is not well formed. Do you want only two char-s combination? Does the input string needs to be 3 char-s wide or can it be whatever? Be sure about that: you risk to produce a code that works on a very specific case, while looking for something more generic.

yes you right.You have any idea about such type of algo because i havn't found algo.Please help me
no, I cannot do your homework.
