C Program to Perform Multiplication

August 2017

A program in the C language can be used to calculate and print a multiplication table in C.

To write a program in C, some knowledge of programming concepts and languages is required. You should also have some familiarity with basic concepts such as looping. Programs that print a multiplication in C can be written using nested for loops, which contains one loop inside another.

C Program to Generate a Multiplication Table

Here's an example of a C table that can perform multiplication:

Result

|   1 2 3  4     
------------------
1 | 1 2 3 4
2 | 2 4 6 8
3 | 3 6 9 12
4 | 4 8 12 16 ...

Code

lami20j@debian:~    
trash$ cat ccm.c
#include<stdio.h>

int
main (void){
int i, j;

printf (" |");
for (i = 1; i < 11; ++i)
printf ("%#3d ", i);
printf ("\n");

for (i = 1; i < 64; ++i)
printf ("-");
printf ("\n");

for (i = 1; i < 11; ++i){
printf ("%#2d |", i);
for (j = 1; j < 11; ++j)
printf ("%#3d ", i * j);
printf ("\n");
}
return 0;
}
lami20j@debian:~/trash$ gcc ccm.c
lami20j@debian:~/trash$ ./a.out
| 1 2 3 4 5 6 7 8 9 10
---------------------------------------------------------------
1 | 1 2 3 4 5 6 7 8 9 10
2 | 2 4 6 8 10 12 14 16 18 20
3 | 3 6 9 12 15 18 21 24 27 30
4 | 4 8 12 16 20 24 28 32 36 40
5 | 5 10 15 20 25 30 35 40 45 50
6 | 6 12 18 24 30 36 42 48 54 60
7 | 7 14 21 28 35 42 49 56 63 70
8 | 8 16 24 32 40 48 56 64 72 80
9 | 9 18 27 36 45 54 63 72 81 90
10 | 10 20 30 40 50 60 70 80 90 100
