Respected sir, extremely thanks to you for give me answer of my question but sir above code has a one problem when i'm input this string "This is a flower" and first word is "is" or second word is "was" then output is "Thwaswas a flower" and i want output like this e.g input string "This is a flower" first word "is " second word "was" then output will be print like this "This was a flower" not like this "Thwaswas a flower"

output after compiling your code

Enter A String: THIS IS A FLOWER Enter First Word: IS Enter Second Word: WAS Replaced String: THWASWASA FLOWER
