I am currently learning C and am facing some issues with the codes below:
typedef struct{
string name;
int age;
bool tall;
}
person;
max_index =3;
person x_1[max_index];
int main(void)
{
//lines of code
while (true)
{
function1();
function2();
}
}
int function1(void)
{
person x_2[max_index];
for (int j=0; j< max_index; j++)
{
if (some conditions)
{
x_2[j].name = x_1[j].name;
x_2[j].age = x_1[j].age;
}
}
}
int function2(void)
{
person x_3[max_index];
for (int j=0; j< max_index; j++)
{
if (some conditions)
{
x_3[j].name = x_1[j].name;
x_3[j].age = x_1[j].age;
}
}
}
- person struct
- a main function that calls function1 and function2 while evaluating certain conditions
- function1 and function2 initialize a new person struct separately - x_2 and x_3
Issue: realise that if the main function calls function1 and function2 > once, the values in x_2 and x_3 remains the same as the previous call. My understanding is since x_2 and x_3 exists only within (local) function1 and function2, each call to both the function will "reset" x_2 and x_3? i.e. a new x_2 and x_3 with each call. But that doesn't seems like the case... I am new to C and not sure what exactly is the issue (unable to google)
Update: indeed, printf helped. There were no issues with the code but rather the debugger was showing wrong variable values.
