Write a C program to accept two strings str1 and str2 and compare them. if they are equal display their length. if str1 > str2 , convert str1 to uppercase and str2 to lowercase and display the strings and vice versa.

#include<stdio.h>

#include<conio.h>

#include<string.h>

#include<process.h>

void main()

{

char str1[30],str2[30],copy[60];

int cmp,length,ch;

clrscr();

            printf("\n Enter a string1 :");

            scanf("\n %s",&str1);

            printf("\n Enter a string2 :");

            scanf("\n %s",&str2);

            cmp=strcmp(str1,str2);

            if(strcmp(str1,str2)==0)

            {

            length=strlen(str1);

             printf("\n string are equals and length is %d",length);

             }

             if(strcmp(str1,str2)>0)

                        {

                        printf("\n string1 is greater");

                        printf("\n string1 in uppercase is %s",strupr(str1));

                        printf("\n string2 in lowercase is %s",strlwr(str2));

                         }

              else

                        {

                         printf("\n string2 is greater");

                        printf("\n string2 in uppercase is %s",strupr(str2));

                        printf("\n string1 in lowercase is %s",strlwr(str1));

             }

getch();

}

/* output

 Enter a string1 :maharashtra

 Enter a string2 :india

 string1 is greater

 string1 in uppercase is MAHARASHTRA

 string2 in lowercase is india */
