Percentage Signs in C and a single {.

Question

I don’t understand why there is always a single bracket of that shape alone in the code after the first or second line. I also don’t get what %2 and %d means please help the Solo Learn explanation confused me.

Answer 1

Any bracket that is opened will be closed or you get syntax error

%d %f etc. specifies what kind of data type the variable is.

%2d is used for reserving space of 2 characters while printing

Eg
printf("%3d",10);
printf("%3d",100);

10
100
