02. Printing more lines

Several printf lines, \n for a new line and \t for a tab: how to lay out text on the screen.

C runs the lines inside main one after another, from top to bottom. Each printf adds to the screen where the last one stopped, so it's \n that starts a new line, not a new printf.

1#include <stdio.h>2
3int main() {4    printf("Ready, ");5    printf("steady, ");6    printf("go!\n");7    printf("One\nTwo\n");8    return 0;9}

It shows

Ready, steady, go!
One
Two

\t is a tab: a jump to the next column, handy for lining things up like a table.

1#include <stdio.h>2
3int main() {4    printf("Item\tPrice\n");5    printf("Idli\t30\n");6    printf("Dosa\t50\n");7    return 0;8}

It shows

Item	Price
Idli	30
Dosa	50

Your turn

1Steps

1Print this little timetable, using \t between the day and the subject and \n at the end of each line:
2Monday tab Maths, then Tuesday tab Science, then Wednesday tab English.

Write it in main.c. If it reads input, put the answers in Program input, under the terminal.

Use: printf()

Starting code

The editor starts empty. Copy this into it to begin, or write your own from scratch.

1#include <stdio.h>2
3int main() {4    printf("Monday Maths Tuesday Science Wednesday English");5    return 0;6}

2Expected output

It should show

Monday	Maths
Tuesday	Science
Wednesday	English

3Hints

Stuck? Open one hint at a time: each gives a bit more help.

Hint 1

Each day needs its own line, so each needs a \n at its end.

Hint 2

Between the day and its subject, use \t instead of a space.

Hint 3

The first line is printf("Monday\tMaths\n"); and the other two are made the same way.
