1 Array Knowledge Understand the execute technique of array Skill Can write application program using one and two dimensional array

2 Why Array? Assume that you were asked to write a program that accept 10 student marks, calculating average mark, and then print a number of students that get more than average mark. How to store all these marks?

#include void main() { int mark1, mark2, mark3, mark4, mark5, mark6, mark7, mark8, mark9, mark10; int bil=0, total_mark = 0; float Average_mark; printf(“\nRead 10 test marks : \n”); scanf(“%d%d%d%d%d%d%d%d%d%d”, &mark1, &mark2, &mark3, &mark4, &mark5, &mark6, &mark7, &mark8, &mark9, &mark10); total_mark = mark1 + mark2 + mark3 + mark4 +mark5 + mark6 + mark7 + mark8 + mark9 + mark10; Average_mark = (float) total_mark/10; Read student marks Solving Without Using Array

#include void main() { int mark1, mark2, mark3, mark4, mark5, mark6, mark7, mark8, mark9, mark10; int bil=0, total_mark = 0; float Average_mark; printf(“\nRead 10 test marks : \n”); scanf(“%d%d%d%d%d%d%d%d%d%d”, &mark1, &mark2, &mark3, &mark4, &mark5, &mark6, &mark7, &mark8, &mark9, &mark10); total_mark = mark1 + mark2 + mark3 + mark4 +mark5 + mark6 + mark7 + mark8 + mark9 + mark10; Average_mark = (float) total_mark/10; Calculate the total mark

Solving Without Using Array Calculate the average mark #include void main() { int mark1, mark2, mark3, mark4, mark5, mark6, mark7, mark8, mark9, mark10; int bil=0, total_mark = 0; float Average_mark; printf(“\nRead 10 test marks : \n”); scanf(“%d%d%d%d%d%d%d%d%d%d”, &mark1, &mark2, &mark3, &mark4, &mark5, &mark6, &mark7, &mark8, &mark9, &mark10); total_mark = mark1 + mark2 + mark3 + mark4 +mark5 + mark6 + mark7 + mark8 + mark9 + mark10; Average_mark = (float) total_mark/10;

if (mark1 > Average_mark) bil++; if (mark2 > Average_mark) bil++; if (mark3 > Average_mark) bil++; if (mark4 > Average_mark) bil++; if (mark5 > Average_mark) bil++; if (mark6 > Average_mark) bil++; if (mark7 > Average_mark) bil++; if (mark8 > Average_mark) bil++; if (mark9 > Average_mark) bil++; if (mark10 > Average_mark) bil++; printf(“\nAverage mark = %.2f”, purata); printf(“\n Number of students that get more than Average mark %d”, bil); } What would happen if there were 100 students? Solving Without Using Array Calculate number of students which get more than Average mark

Solving Without Using Array if (mark1 > Average_mark) bil++; if (mark2 > Average_mark) bil++; if (mark3 > Average_mark) bil++; if (mark4 > Average_mark) bil++; if (mark5 > Average_mark) bil++; if (mark6 > Average_mark) bil++; if (mark7 > Average_mark) bil++; if (mark8 > Average_mark) bil++; if (mark9 > Average_mark) bil++; if (mark10 > Average_mark) bil++; printf(“\nAverage mark = %.2f”, Average_mark); printf(“\n Number of students that get more than average mark = %d”, bil); } What would happen if there were 100 students? Print the result

8 One-dimensional Array Instead of using 10 variables to represent 10 student marks,another technique is using one-dimensional array for storing a list of marks. Array is a collection of memory location that is used for storing data from same type. Each memory location in array is referred by array’s name and location memory index.

9 One Dimensional Array 67 mark [0] [1] [2] [3] [4] [5] [6] [7] [8] [9] For printing each mark in array: for (i=0; i < 10; i++) printf("%d ", mark[i]) Array name

10 One Dimensional Array 67 mark [0] [1] [2] [3] [4] [5] [6] [7] [8] [9] For printing each mark in array: for (i=0; i < 10; i++) printf("%d ", mark[i]) Array Index

11 One-Dimensional Array Array declaration syntax data_type name_of_array[integer_expression]; Example: int mark[10]; In C programming, each index in array is start from 0. Thus, the last index number in one array of sized n is n-1.

12 Array Controlling One way for giving initial value to array’s element is giving a list of initial value in array declaration.

13 Array Controlling Example: int month[12] = { 31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31 }; month [0] [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11]

14 Array Controlling If the list of initial value is less than array size, the rest element will be given 0 value int month[12] = { 31, 28, 31, 30, 31 } month [0] [1] [2] [3] [4] [5] [6] [7] [8] [9] 0 0 [10] [11]

15 Array Controlling Array size can be ignore in declaration if it is given by initial value list. Array size will be set based on a number of data in their list. int month[ ] = { 31, 28, 31, 30, 31 } month [0] [1] [2] [3] [4]

16 Array Assignment Value assignment to array’s element is same as value assign to variable. Assignment to array can be done element by element.

17 Array Assignment Example: tinggi ??? [0] [1] [2] [3] [4] float tinggi[5]; tinggi[0] = 31.34; tinggi[1] = 28.11; tinggi[2] = 31.25; tinggi[3] = 30.94; tinggi[4] = 31.68;
