The instruction supply this code block.
In the first line in main() func there’s something which may be an invalid integer declaration.
Did I get it wrong?

``````void myFunc(int* a){
*a = *a+2;
printf("a inside myFunc(): %d\n", *a);
}

int main(){
a = 10;  // < -- RIGHT HERE
int* aPointer = &a;
myFunc(aPointer);
printf(“a in main(): %d\n”, a);
}
``````
