1. INC 161 , CPE 100 Computer Programming
Lab 11

2. Task 1
#include <stdio.h>
// Write you function here
main() {
int i = 2;
increase(&i);
printf(“i = %d”,i); }
From the code given, write a function so that the program +2 and print i = 4.
You must not change anything in main().

3. Task 2
#include <stdio.h>
// Write you function here
main() {
int i = 2;
i = increase(i);
printf(“i = %d”,i); }
From the code given, write a function so that the program +2 and print i = 4.
You must not change anything in main().

4. Task 3
#include <stdio.h>
// Write you function here
main() {
int a = 12, b = 16, c = 20, d;
hcf(a,b,c,&d);
printf(“HCF = %d”,d); }
From the code given, write a function so that the program calculate the highest common factor
(ห.ร.ม.) of a,b,c and get the result to d .
You can assume that a,b,c are less than 1000

5. Write a flowchart first.
e.g. a,b,c = 2,4,8
Assume start from 10 (for short)
2,4,8 is divisible by 10 – no
2,4,8 is divisible by 9 - no
2,4,8 is divisible by 8 - no
2,4,8 is divisible by 7 - no
2,4,8 is divisible by 6 - no
2,4,8 is divisible by 5 - no
2,4,8 is divisible by 4 - no
2,4,8 is divisible by 3 - no
2,4,8 is divisible by 2 – yes - >stop

6. Task 4
#include <stdio.h>
// Write you function here
main() {
int a = 12, b = 16, c = 20, d;
d = hcf(a,b,c);
printf(“HCF = %d”,d); }
From the code given, write a function so that the program calculate the highest common factor
(ห.ร.ม.) of a,b,c and get the result to d .
You can assume that a,b,c are less than 1000
