How to write a C Program to Print Elements in an Array using For Loop, While Loop, and Functions with example.
C Program to Print Elements in an Array
This program to print an array in c allows the user to enter the Size and the row elements of One Dimensional Array. Next, we are using For Loop to iterate the array values and print all the elements in this array
/* C Program to Print Elements in an Array using For Loop */
#include <stdio.h>
int main()
{
int Array[50], i, Number;
printf("\nPlease Enter Number of elements in an array : ");
scanf("%d", &Number);
printf("\nPlease Enter %d elements of an Array \n", Number);
for (i = 0; i < Number; i++)
{
scanf("%d", &Array[i]);
}
printf("\n Elemenst in this Array are :\n");
for (i = 0; i < Number; i++)
{
printf("%d\t", Array[i]);
}
return 0;
}OUTPUT
ANALYSIS
This program to print an array in c, the For Loop will make sure that the number is between 0 and maximum size value. In this example, it will be from 0 to 7
for(i = 0; i < Size; i ++)
First Iteration: for (i = 0; 0 < 5; 0++)
Condition is True so, the compiler will print first element(10) in an array
Second Iteration: for (i = 1; 1 < 5; 1++)
Condition is True so, compiler prints second element (75) in an array
Third Iteration: for (i = 2; 2 < 5; 2++)
Condition is True so, compiler will print third second element (89) in an array
Fourth Iteration: for (i = 3; 3 < 5; 3++)
Condition is True so, compiler will print fourth element (62) in an array
Fifth Iteration: for (i = 4; 4 < 5; 4++)
Condition is True so, compiler will print fourth element (12) in an array
Sixth Iteration: for (i = 5; 5 < 5; 5++)
Condition is False so, compiler will exit from the for loop
Program to Print Elements in an Array using While Loop
This program of how to print an array is the same as above. But this time we used While Loop to print array elements
/* C Program to Print Elements in an Array using While Loop */
#include <stdio.h>
int main()
{
int Array[50], i = 0, j = 0, Number;
printf("\nPlease Enter Number of elements in an array : ");
scanf("%d", &Number);
printf("\nPlease Enter %d elements of an Array \n", Number);
while (i < Number)
{
scanf("%d", &Array[i]);
i++;
}
printf("\n **** Elemenst in this Array are : ****\n");
while (j < Number)
{
printf(" Element at Array[%d] = %d \n", j, Array[j]);
j++;
}
return 0;
}OUTPUT
Program to Print Elements in an Array using Functions
This program to print an array in c is the same as the first example. However, we separated the logic to print array elements using Functions.
/* C Program to Print Elements in an Array using Functions */
#include <stdio.h>
void PrintArray(int a[], int Size);
int main()
{
int Array[50], i, Number;
printf("\nPlease Enter Number of elements in an array : ");
scanf("%d", &Number);
printf("\nPlease Enter %d elements of an Array \n", Number);
for (i = 0; i < Number; i++)
{
scanf("%d", &Array[i]);
}
PrintArray(Array, Number);
return 0;
}
void PrintArray(int a[], int Size)
{
int i;
printf("\n **** Elemenst in this Array are : ****\n");
for (i = 0; i < Size; i++)
{
printf(" Element at Array[%d] = %d \n", i, a[i]);
}
}OUTPUT
Program to Print Elements in an Array using Recursion
This print an array program is the same as the above, but this time we used the Recursion concept.
/* C Program to Print Elements in an Array */
#include <stdio.h>
void PrintArray(int arr[], int Start, int Size);
int main()
{
int Array[50], i, Number;
printf("\nPlease Enter Number of elements in an array : ");
scanf("%d", &Number);
printf("\nPlease Enter %d elements of an Array \n", Number);
for (i = 0; i < Number; i++)
{
scanf("%d", &Array[i]);
}
printf("\n **** Elemenst in this Array are : ****\n");
PrintArray(Array, 0, Number);
return 0;
}
void PrintArray(int arr[], int Start, int Size)
{
if(Start >= Size)
{
return;
}
printf(" Element at Array[%d] = %d \n", Start, arr[Start]);
PrintArray(arr, Start + 1, Size);
}OUTPUT
