#include <stdio.h>
int main(void) {
int i;
i = 10;
i*= 10+2;
printf("%d",i);
return 0;
}
why is the output of the following code 120 and not 102?
Because the order of precedence makes '+' higher than *=, so the 10+2 will occur befor the i *=.
C reference for ordering at http://en.cppreference.com/w/c/language/operator_precedence
In this Line i*= 10+2; In this case the 12 multiply by i It Means i=10*12; So it Will Give 120 In answer
To solve this issue Try This.
i*= 10;
i+=2;
your code work like .
i= i*(10+2)
so it give the answer like 120.
if you wanna answer like 102 the do .
i=i*10+2
This
i*= 10 + 2;
is syntactic sugar for
i= i * (10 + 2);
the rest is precedence left to right, add and subst after mult./division
