Simple C Program with Algorithm, Flowchart, Output - Computer Programming - C

Write a program to concatenate two strings using dynamic memory allocation.

AIM

To write a program to concatenate two strings.

ALGORITHM

Step‒1 : Start

Step-2 : Read two string into s1,s2

Step-3 : Allocate memory for s1,s2,s3

Step-4 : Store each character of the string s1 into an array

Step-5 : Store each character of the string s2 into another array

Step-6 : Combine both arrays into one

Step-7 : Print Concatenated string

Step-8 : Stop

FLOWCHART

PROGRAM

#include<stdio.h>

#include<conio.h>

#include<malloc.h>

#define lenght 40

void main()

{

char *s1, *s2,*s3,c;

int i,j,k;

clrscr();

s1=(char*)malloc(lenght * sizeof(char));

s2=(char*)malloc(lenght * sizeof(char));

s3=(char*)malloc(2 *lenght* sizeof(char));

printf("Enter string one :");

scanf("%s",s1);

printf("Enter string two :");

scanf("%s",s2);

i=0;

while((c=*(s1+i))!= '\0')

{

s3[i]=c;

i=i+1;

}

k=0;

while((c=*(s2+k)) != '\0')

{

s3[i+k]=c;

k=k+1;

}

printf("Concatenated string is: \n");

printf("%s\n",s3);

getch();

}

OUTPUT

Enter string one: Muni

Enter string two : Rathnam

Concatenated string is :

Muni Rathnam
