jumble function is just taking 2 arguments say arg1 and arg2. and returning (2*arg1) + arg2
in main function we have below:
y=jumble(5,2);---main called jumble function with arguments 5,2 initially and result was stored in variable y
here y becomes 12 i.e: (2*10)+2
x remains same which is 2
x=jumble(12, 2);----main again called jumble function with arguments 12,2 and stored in variable x
so x becomes 26 i.e: (2*12)+2
finally x will be printed
output: 26
