5. Program to demonstrate string functions.

#include<stdio.h>

void main()

{

char str1[20] = "Peopletree",str2[20]="BCA";

printf("Length of string %s is: %ld\n",str1,strlen(str1));

printf("Length of string %s is: %ld\n",str2,strlen(str2));

printf("First string after concatenation: %s\n", strcat(str1,str2));

printf("First string after copying: %s\n", strcpy(str1,str2));

if (strcmp(str1, str2) ==0)

printf("string 1 and string 2 are equal\n");

else

printf("string 1 and 2 are not equal\n");

}
