Input 10 numbers in 1d array and interchange the consecutive numbers in C
One Dimensional Array - Question 8
In this question, we will see how to input 10 numbers in a one dimensional integer array and interchange the consecutive numbers in it in C programming. To know more about one dimensional array click on the one dimensional array lesson.
Q8) Write a program in C to input 10 numbers in a one dimensional integer array and interchange the consecutive numbers in it. That is, interchange a[0] with a[1], a[2] with a[3], a[4] with a[5] and so on.
Program
#include <stdio.h>
#include <conio.h>
int main()
{
int a[10], i,t;
printf("Enter 10 numbers\n");
for(i=0; i<10; i++)
{
scanf("%d",&a[i]);
}
//Interchanging the consecutive numbers in array
for(i=0; i<10; i=i+2)
{
t=a[i];
a[i]=a[i+1];
a[i+1]=t;
}
printf("\nModified array after interchanging the consecutive numbers\n");
for(i=0; i<10; i++)
{
printf("%d ",a[i]);
}
return 0;
}Output
Enter 10 numbers 18 12 5 10 15 45 38 72 64 11 Modified array after interchanging the consecutive numbers 12 18 10 5 45 15 72 38 11 64
