Addition of the elements of the list
#include<stdio.h>
#include<conio.h>
void main()
{
int a[5],i = 5,sum=0;
printf("Enter the elements of list \n");
int j;
for(j=0;j<i;j++)
scanf("%d",&a[j]);
fflush(stdin);
printf("The list elements are \n");
for(j=0;j<i;j++)
printf("%d ",a[j]);
printf("\n");
for(i=0;i<5;i++)
{
sum+=a[i];
}
printf("The sum of the elements of the list is %d\n",sum);
}Enter the elements of list 1 2 3 4 5 The list elements are 1 2 3 4 5 The sum of the elements of the list is 15
Address of each element in an array
Array elements occupy consecutive memory locations.
#include <stdio.h>
main()
{
int a[5];
int i;
for(i = 0;i<5;i++)
{
a[i]=i;
}
for(i = 0;i<5;i++)
{
printf("value in array %d\n",a[i]);
}
for(i = 0;i<5;i++)
{
printf("value in array %d and address is %16lu\n",a[i],&a[i]);
}
}value in array 0
value in array 1
value in array 2
value in array 3
value in array 4
value in array 0 and address is 631656
value in array 1 and address is 631660
value in array 2 and address is 631664
value in array 3 and address is 631668
value in array 4 and address is 631672
Arrays
An array is a data structure process multiple elements with the same data type.
Array elements are accessed using subscript.
The valid range of subscript is 0 to size -1.
#include <stdio.h>
main()
{
int a[5];
int i;
for(i = 0;i<5;i++)
{
a[i]=i;
}
for(i = 0;i<5;i++)
{
printf("value in array %d\n",a[i]);
}
}value in array 0
value in array 1
value in array 2
value in array 3
value in array 4
