[SOLVED] Little confusion on while/ do while loop in C.

Question

Here in my code, I tried to place the increment operator inside printf() to reduce the lines of code by removing the { braces.

int i = 201;
while(i <= 300)
printf("%d\t", i, i++);

And.

i = 201;
do
printf("%d\t", i, i++);
while(i <= 300);

Is this a valid way to do and how does this work?

Answer 1

Try this printf("%d\t",i++); it will print current value and increment as your need

Answer 2

Why don't you try it on your own on code playground to see wether it is valid or not👇
