What is the difference between a[n+1] and a[n]+1 inside an array? -

i looked , looked on website find answer couldnt find anywhere.

however, difference?

here think.

say have array 5 elements in it, a[5]. a[n+1] second element, a[n+2] third, etc.

a[n]+1 be, type in number first element [n]. number 27, since a[n]+1 equal 28.

a[n]+ 1 takes value a[n] , adds 1 it.

a[n+1] takes value of n , adds 1 it.

bothe different in meaning context. a[n+1] index increment , value retrieval specified list , index. a[n] + 1 value retrieval specified list , index adding 1 it.

for example,

a = [1,2,3,4,5]  n = 2  a[n+1] a[2+1] => a[3] => 4  a[n] + 1 a[2] + 1 => 3 + 1 => 4
