cin>>t;
a=t%10;
while(t!=0)
{
b=t%10;
t=t/10;
}
y[i]=a+b;

What Problem are you trying to solve?

[sultan07]

If Give an integer N . Write a program to obtain the sum of the first and last digits of this number.

@sultan07

int x,y[10];

@sultan07

for(i=0;i<n;i++)
{y[i]=0;

What if n \gt 10 ? (Given that the number of test cases can go up to 1000).

[sultan07]

yes we can change 10 to 1000 in that case
