looks like you are first time user.
Few point i would like to add.
Credit card has their own pro and cons
Pros,
you dont have to actually have money always
CC comes handy during month ends even when you dont have money.
cc comes with reward points which you can either claim for cash or some goodies depends on the type of card you have.
if you spend wisely you can earn a lots of rewards
CC increases your credit scores( provided you pay them on time), which helps when you go for loans.
CONs:
Credit card banks put a huge penalty when you dont pay on time( never ever pay minimum due, always pay your credit bill in time and in full)
you will overspend as you have a huge credit limit than you actually need
Dont use CC just for rewards, as you will overspend if you do that way
Better go for a zero annaul fee card if you can, incase you will have to travel abroad for a year or more you dont have to pay annual fee till you come.
Never withdraw cash with CC( there is a huge charge for cash withdrawal)
Read all the terms and conditions of the CC before you use it.
CC are good ones if you use them wisely
