Slip 3 - B) Write a menu driven program to perform the following operations on strings using standard library functions: 1. Length of String 2. Copy String 3. Connect Two Strings 4. Compare two strings

Solution:

#include<stdio.h>

#include<conio.h>

#include<string.h>

  void main()

{

  char str[20],str1[20];

  int ch,i,j;

  clrscr();

  do

{

  printf("\n****MENU****");

  printf("\n1:Find Length");

  printf("\n2:Copy the Strings");

  printf("\n3:Compare the Strings");

  printf("\n4:Concatenate the Strings");

  printf("\n5:Exit");

  printf("\nEnter your choice: ");

  scanf("%d",&ch);

  switch(ch)

{

  case 1:

    printf("\nEnter the string: ");

    scanf("%s",&str);

    i=strlen(str);

    printf("\nThe Length of given string is: %d",i);

    break;

  case 2:

    printf("\nEnter the first string: ");

    scanf("%s",&str);

    printf("\nEnter the second string: ");

    scanf("%s",&str1);

    strcpy(str,str1);

    printf("\nThe Copied string is: %s",str);

    break;

  case 3:

    printf("\nEnter the first string: ");

    scanf("%s",&str);

    printf("\nEnter the second string: ");

    scanf("%s",&str1);

    j=strcmp(str,str1);

    if(j==0)

  {

    printf("\nThe string is same");

  }

    else

  {

    printf("\nThe string is not same");

  }

    break;

  case 4:

    printf("\nEnter the first string: ");

    scanf("%s",&str);

    printf("\nEnter the second string: ");

    scanf("%s",&str1);

    strcat(str,str1);

    printf("\nThe Concatenated string is: %s",str);

    break;

  case 5:

    exit(0);

    break;

}

}

  while(ch!=5);

  getch();

}
