Converting an integer to string

[geeta719]

void main()
{
char ch[10]="";
char c;
int k=0,l,i;
printf("Enter a number:");
scanf("%d",&i);
while(i!=0) //reversing a numbr
{ k=k*10+i%10;
i=i/10;}

while(k!=0) //converting a number to string
{ c=48+k%10;
strcat(ch,&c);
k=k/10;}
printf("\n%s",c h);
}

its posing an error of abnormal termination and not getting output as expected!!

That is because strcat expects a pointer to a C style string and not a pointer to a single character.

Why not just printf using the %d format specifier and print the number directly.

Using 48 to denote the character '0' is very poor. What happens if you compile this program on a platform that uses a character set where '0' doesn't have the value 48?

And finally you reverse the string twice so if you get this program working it will output what was input.

actually i want to convert an input integer to string......sin ce we can concatenate at the back of first string ,therefore first i m reversing the string and den using caoncatenation

What is your purpose for this?

It would be just as easy to accept a string as input and then check that all the characters were digits as it would be to accept an integer and convert it to a string since basically all input from the keyboard starts as a string anyway.

There are plenty of functions that will convert a string to an integer and an integer to a string for you.

printf("\n%s",c h);
ch is an array
