# how to do addition with in an array , save to another but condition is the sum of value in 2nd array should not less than or equal to 15.? and my program going to infinite loop..

Asked by preet on 13 Mar 2013

a=[2,14,23,12,4,4,10,1]

if there is any value in the array a() is less than or equal to 15 than that will add to next value of same array and store in the another array b(). each value in b() should be more than 15 at last if there is no value in the array a() and the addition is less than equal to 15 then the result of addition will add to the previous value to the array b().

```a=[2,14,23,12,4,4,10,1];
```
```index=1;i=1;
```
```while (i<=8)
```
`      if(a(i)>15)`
```          b(index)=a(i);
index=index+1;
else
value=a(i);
j=i;
while(value<=15)
if(j<8)
j=j+1;
value=value+a(j);
% j=j+1;
else
break;
end
end
i=j+1;
if(value>15)```
```              b(index)=value;
index=index+1;
else
b(index)=b(index)+value;
end
end
end```

and my answer after to implment it. infinite loop going on. my answer should be b=[31,23,16]

I don't get how you aggregate a ..

The b that you provide seems to be the outcome of

` b = [1+10+4+4+12, 23, 14+2]`

and I don't understand why the reverse order. Also, I could propose

` b = [1+10+4+4, 12+23, 14+2] = [19, 35, 16]`

which would match the criterion b(i) > 15. Can you provide more information about the logic behind the way you aggregated your solution?

if a=[1,14,23,12,4,4,10,1]

then [15, 35,16] so should i add 15+35 or 15+16?

Well, it is up to you to perfectly know/define what you want to compute and how. Then we can help you writing MATLAB code (or improving it) for that.
