code for concatination of 2 strings with out using library functions?..

Answer / kiruthikau

[code]
#include<stdio.h>
#include<string.h>
main()
{
char one[]="hai";
char two[]=" hello";
int len1=strlen(one);
int len2=strlen(two);
char res[len1+len2];
int i,j;
for(i=0;i<len1;i++)
res[i]=one[i];
for(j=0;j<len2,i<len1+len2;i++,j++)
res[i]=two[j];
res[i]='\0';
printf("res:%s\n",res);
}
[/code]

If you don't want to use strlen() function also ,try the
following code.

[code]
#include<stdio.h>
#include<string.h>
main()
{
char one[]="hai";
char two[]=" hello";
int len1=0;
int len2=0;
int i=0;
int j;
while(one[i++]!='\0')
len1++;
i=0;
while(two[i++]!='\0')
len2++;
char res[len1+len2];
for(i=0;i<len1;i++)
res[i]=one[i];
for(j=0;j<len2,i<len1+len2;i++,j++)
res[i]=two[j];
res[i]='\0';
printf("res:%s\n",res);
}
[/code]

void strrcat(char *a , char *b)
{
for(int i=0;*a!='\0';i++,a++);
