If i write num= 1 and (num<6) and num=num +1 the value comes 1-5 and if i wrote num=num+3 the value comes 1and 4 why this so

Question

i m a bit confuse as in first case 5 numbers arrive but in second only two why this so

Answer 1

Do you iterate in a loop? If yes then what happens is:
Num = 1 <6 yes; +=1; output 2
Num = 2 <6 yes; += 1 output 3
...
Num= 5 <6 yes; += 1 output 5
Num = 6 <6 no stop, no output

For the other case its more exreme. 1+3 is 4 (output 4), 4 + 3 is 7 (no output).

Does that make sense?
