C array reverse
Example - Reverse an array
#include<stdio.h>
#include<conio.h>
void read(int *,int);
void dis(int *,int);
void inverse(int *,int);
//from w w w . j ava 2s . c om
main(){
int a[5],i;
read(a,5);
dis(a,5);
inverse(a,5);
dis(a,5);
getch();
}
void read(int c[],int i)
{
int j;
printf("Enter the list \n");
for(j=0;j<i;j++)
scanf("%d",&c[j]);
fflush(stdin);
}
void dis(int d[],int i)
{
int j;
printf("The list is \n");
for(j=0;j<i;j++)
printf("%d ",d[j]);
printf("\n");
}
void inverse(int inver_a[],int j)
{
int i,temp;
j--;
for(i=0;i<(j/2);i++)
{
temp=inver_a[i];
inver_a[i]=inver_a[j];
inver_a[j]=temp;
j--;
}
}
The code above generates the following result.
Example - Use another list to hold the reversed list
#include<stdio.h>
#include<conio.h>
//w w w.j av a 2 s. co m
void read(int *,int);
void dis(int *,int);
void inverse(int *,int *,int);
main(){
int a[5],b[5];
read(a,5);
dis(a,5);
inverse(a,b,5);
dis(b,5);
getch();
}
void read(int c[],int i)
{
int j;
printf("Enter the list \n");
for(j=0;j<i;j++)
scanf("%d",&c[j]);
fflush(stdin);
}
void dis(int d[],int i)
{
int j;
printf("The list is \n");
for(j=0;j<i;j++)
printf("%d ",d[j]);
printf("\n");
}
void inverse(int a[],int inverse_b[],int j)
{
int i,k;
k=j-1;
for(i=0;i<j;i++)
{
inverse_b[i]=a[k];
k--;
}
}
The code above generates the following result.
