{

scanf(“%d”,&a[i]);

sum=sum+a[i];

}

printf(“The given arrays is: “);

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

printf(“%d”,a[i]);

a[2]=a[1]*a[n-1];

printf(“\n the given areay after replacing

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

printf(“%d”,a[i]);

a[(1+n/2)]=sum/n;

printf(“\n the given array after replacing

middle element by average of all”);

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

if(a[i]<0)

a[i]=0;

printf(“\n given array after replacing –ve

values by zero”);

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