局部变量在函数中定义,例如main()
函数。
#include <stdio.h>
int main() {
int num1;
printf("\nEnter a number: ");
scanf("%d", &num1);
printf("\nYou entered %d\n ", num1);
return 0;
}
局部范围变量与其原始函数相关联,可以在其他函数中重用变量名称。
#include <stdio.h>
int getSecondNumber(); //function prototype
int main()
{
int num1;
printf("\nEnter a number: ");
scanf("%d", &num1);
printf("\nYou entered %d and %d\n ", num1, getSecondNumber());
}
int getSecondNumber ()
{
int num1;
printf("\nEnter a second number: ");
scanf("%d", &num1);
return num1;
}
