#### Program

```
from array import *
t=0
a=array('i',[])
print('Enter 10 numbers')
for i in range(10):
a.append(int(input()))
for i in range(0,10,2):
t=a[i]
a[i]=a[i+1]
a[i+1]=t
print('\nModified array after interchanging the consecutive numbers');
for n in a:
print(n,end=' ')
```

#### 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
