Question

Computer science
Can anyone send me the answers of these sums 12 part.

Answer 1

pre-increment(++) or pre-decrement(--)[before identifier]::we had to increment the variable value by one(++) or decrement by value one(--) and then evaluate that expression....

example:

a=12;
b=++a;
System.out.println(b);
output:13

post-increment( after identifier ++)or post-decrement( after identifier --):::we had to evaluate expersion first then increment the variable value by one(++) or decrement value by one(--).

a=12;
b=a++;
System.out.println(b);
output:12

note: increme

using this rule.....

output.....

1) a=12+11+12=35

2)b=13+13*2=13+26=39

3)c=11+12*(14)=11+168=179

4)b=13+15+11+13=52

5)a=179
