I started to learn arduino code not too long ago and I started this project where with a press of a button I can change the numbers on a 7-segment display, at the moment I got to the point of turning on a number with a button but I don't know how to latch the number as well as having a latch counter so the arduino could count the amount of times the button has been pushed in order output the corresponding number.
That's not going to work for someone to help you and it's not all the code 
. The best thing to do is to highlight all the code in the Arduino IDE, copy it, and then paste it into a reply here. When you've pasted it, select it all and using the Tools drop down at the bottom of the reply box, select Source Code, as shown below. That should format it to make it easy to read. TBH, I've not tried adding source code to a reply so I assume that will work: try and play around with it if not. Anyway, the idea is that we get the code not a screenshot!
For inserting source code use Insert/ </> Code option
void setup() {
// put your setup code here, to run once:
}
void loop() {
// put your main code here, to run repeatedly:
}
