String Concatenate Without Using Library Function

Here in this video i have explained about how to concatenate two strings without using the Library Functions..Enjoy!!

[vishwambharkale]

you explains very nicely, do something with background sound

[sidh]

well done
but i wish if the bgm is not there it will be the excellent class

I think the i++ in 1st for loop is not because we already increment the value of i in the for. I discovered that when i using the i++ again in the 1st for loop body, it gives a garbage value in the place of the 1st string in the output.

[damanjotsingh]

Why we doing i++, j++ and how they re joined

[sumapathiraj]

Every thing is good but what the thing about the sound background

* Assignment 5*/
/*Q7. Write a program to perform String manipulations (without using built in
functions)
a. String copy
b. String concatenation
c. String compare
*/

//a. String copy

#include <stdio.h>
#include <stdlib.h>

int main(int argc, char *argv[])
{
char s1[50];
char s2[50];
char s3[100];

int i=0, j=0;

printf("Enter the s1 string:");
gets(s1);
printf("Enter the s2 string:");
gets(s2);
fflush(stdin);
for(i=0;s1[i]!='\0';i++)
{
s3[i]=s1[i];
}
for(j=0;s2[j]!='\0';j++)
{
s3[i++]=s2[j];
}
s3[i]='\0';
printf("the string s1;%s is concatenate with s2:%s is s3:%s\n ", s1, s2, s3);
fflush(stdout);

return (EXIT_SUCCESS);
}


please do correction sir.

U explained really well. Thanx a lot. Do update all the programs, that will be really helpful.

[sachingoel]

the output is only one character, two string is not concatenating. pls give me answer.

[misbahpathan]

Sir,
was it necessary to increment i inside first for loop(after storing value of a[i] in c[i]).

[rajatprakash]

Incrementing I again in for loop(i part) is creating problem, remove it and the code will run perfectly

[singh]

sir there is error in this code is tnot running properly i m Entering Ayush in first String n Singh in second String the output is coming is A only

[BhushanDhage]

can u plzz explain how how to find string is pallindrome or not without using strrev????

[vk]

you are a very good teacher..
can u upload tutorials based on pattern programming...pls

[v-yugito]

hey sir could u make a video on class 11 cbse structure data type array c++.normal once.not with scan f thingy only that cout cin return 0 header file if loop etc

[rounak]

instead of writting \o we can only write b[i] ...ascii value of null is 0...thats the reason

[zerotoherocoder-]

How to give space between hello and john after concatenate?

[varshuvarshit]

is it compulsory to add the null to the c[i] at the end?

[adityarajora]

how you can use i out of the scope of its your program gives lots of error in Dev c++

[sachingoel]

Hi finally i find error in my code, i think i must be necessary to initialize the variables first instead of declaration. Thanks you Karthik.

[tusharkumar]

why we are using "i" in the second string??
