In what context I should use " I got to say " and " I want to say ". Someone tell me with suitable examples.
First of all, the proper phrase is "I've got to say", or "I have got to say." (The present perfect tense is required in this case.)
"I've got to say" means that the speaker feels very firmly in what he is stating. He is absolute in his conviction.
Examples: "I've got to say that this is the best birthday present I've ever received!"
"I've got to say that you're wrong - Daryl Dixon is the best character on The Walking Dead. He can hunt, he can track, and he's totally hot, too."
"I've got to say that unless we reduce our labor costs, our company will lose money in the next quarter. Our competitors are importing products from countries with no minimum wage laws."
Depending upon the context, "I want to say" can indicate that the speaker is unsure of his facts when he is expressing an opinion.
Examples: Question: "What day did you move into that house?" Answer: "I want to say May 30, but I'd have to check my calendar to be sure. I know it was around Memorial Day."
Or a speaker could use "I want to say" as a preface for some further opinions or thoughts he is going to express...
Examples: (Recipient of an award, speaking from a podium): "I want to say 'thank you' for this honor. I could not have accomplished this without the assistance of a great many people...."
(Member of a committee that is about to vote on an issue): "I want to say that I think we're making a big mistake if we close the public libraries on Saturdays."

Cross-posting aside, it's always a good idea for the first responder to encourage the OP to make their own sentences, rather than handing out an answer. For future reference.
