OOP CPP Programming language Array by Nadir Nadeem: Part-4
Array in c/cpp(c++):
Array:
- Store more than one values in a single variable.
- Array index start from zero
Syntax:
Datatype variable[]; à int x[]
Datatype variable[size]; à int x[4];
2D Array:
Syntax:
Datatype variable[][]; à int x[][];
Datatype variable[size][size]; à int x[3][4];
Example:
int x[]={12,461,753,6};
x:
values |
12 |
461 |
753 |
6 |
index |
0 |
1 |
2 |
3 |
Example:
17,18,19,20,21,22,23,24,25 è with also while loop
26,27,28,29,30,31,32,33,34
Ass#35,36: print variable value in [] à for and while
x[0]= 12
x[1]=461
Array:
Syntax:
Datatype varisble[];
Datatype variable[size in int];
Datatype variable[]={v1,v2,v3…};
Int x[]={10,20,30,40};
X:
values |
10 |
20 |
30 |
40 |
Index |
0 |
1 |
2 |
3 |
Example:
Example:
Example:
Example with loop:
Example:
Example:
2D Array:
Syntax:
Datatype variable[size][size];
Datatype variable[size][size]={{},{},…};
Example:
Example: with loop
Example:
Ass#38: Sum of required values:
How many values you want to sum: = 4
Enter v1= 3
Enter v2 = 2
Enter v3 = 2
Enter v4 = 4
3,2,2,4 values have sum = 11
Ass#40: Calculate the average
How many values you want to calculate average: = 4
Enter v1= 3
Enter v2 = 3
Enter v3 = 3
Enter v4 = 3
The average of above values := 3
