This is a very quick question. Why am I allowed to do this:
char* sentence[2] ={"blahblah","trololo"};
int main() {
printf("%s",sentence[0]);
printf("%s",sentence[1]);
return 0;
}
but not this?:
char* sentence[2];
sentence[0] = "blahblah";
sentence[1] = "trololo";
int main() {
printf("%s",sentence[0]);
printf("%s",sentence[1]);
return 0;
}
You're not allowed to do the second part, because the assignment is outside of a function. When you move the assignment into main() (or another function), it will be valid
char* sentence[2];
int main() {
sentence[0] = "blahblah";
sentence[1] = "trololo";
printf("%s",sentence[0]);
printf("%s",sentence[1]);
return 0;
}
Why am I allowed to do this:
char* sentence[2] ={"blahblah","trololo"};
Initialization is allowed for global variables.
but not this?:
The statements
sentence[0] = "blahblah";
sentence[1] = "trololo";
makes no sense outside a function ( main() ). Move them inside the function and it will work.
Sorry i didnt read in a correct way the question and i didnt see the function main()
the code works every time inside the functions. the functions have to be called! main is called by the system. so this code is not attainable.
you can put out from the functions just global variable (example costant) or struct.
