To traverse an array in five different ways

To traverse an array in five different ways

#include <iostream>

using namespace Std;

int main ()

{

int sum[5]={0};

int iarray[]={1,2,3,4,5,6,7,8,9,10}; A new method of finding the length of an array, where IArray represents the beginning of the array,

int size=sizeof (IArray)/sizeof (*iarray); So sizeof (IArray) represents the length of this array, and sizeof (* (iarray+0)) represents the length of the first space

int *iptr=iarray;

int n;

for (n=0;n<size;n++)

{

Sum[1]+=iarray[n];

}

for (n=0;n<size;n++)

{

sum[0]+=* (Iarray+n);

}

for (n=0;n<size;n++)

{

Sum[2]+=iptr[n];

}

for (n=0;n<size;n++)

{

sum[3]+=* (Iptr+n);

}

for (n=0;n<size;n++)

{

sum[4]+=*iptr++;

}

for (n=0;n<5;n++)

{

cout<<sum[n]<<endl;

}

return 0;
