Output:-

 

Enter the string1=Lalit

Enter the string2=Rohilla

 

 

 Menu

 

1. String Length=

 

2. String Concat=

 

3. String Reverse=

 

4. String copy=

 

Enter the choice(1-4)=1

It’s length is 12

 

Do you want to continue(y/n)y

 

Enter the choice(1-4)=2

LalitRohilla

 

Do you want to continue(y/n)y

 

Enter the choice(1-4)=3

The reverse string1 is=tilaL

The reverse string2 in=allihoR
