//total up the array
//total + = total + a[i]
total += a[i]

but, tehre is b,c,d,e,f ..i diont know ho w to do

You want a(i) + b(i) + c(i) + d(i) + e(i) = 10 right?

You try something like this:

[code=c]
int total = 0;
for(int i = 0;i<10;i++)
{
total = a[i] + b[i] + c[i] + d[i] + e[i];
if(total==10)
{
printf("total is 10");
}
total=0;
}
[/code]

Why must total=0;?

and why == ?

printf("total is 10");
}
total=0;
}

[amitpatel66]

Why must total=0;?

and why == ?

printf("total is 10");
}
total=0;
}

== is a relational operator used in IF for comparison. You can learn about fundamentals of C here

And regarding total = 0, I have reinitialized the total variable so that next time it will store the sum for second value ie for i = 1 and so on.
Its always good to reinitialize/clear a variable value before using them again
