当我去编译下面的程序时出现这个错误,我不明白为什么。
39:19: error: invalid operands of types ‘const char [5]’ and ‘long long int’ to binary ‘operator&’
这是代码。
int
main(void)
{
long long d, p;
// Ask for number for the numbers of days as long as input is between 28 and 31
do
{
printf("How many days are in your month?\n");
scanf("%lld" &d); // This is the line with the error
}
while (d<28 || d>31);
// Ask user for number of pennies for day 1 as long as input is not negative
printf("How many Pennies do you have?\n");
do
{
scanf("%lld", &p);
}
while (p<0);
//sum up the pennies
int i;
for (int i=0; i<=d-1; i++);
{
p = (p * 2);
}
// Format and print the total (currently * instead of / for troube-shooting)
double total;
total = (p * 100);
printf("Your ending amount it $%.2f.\n, total");
}
最佳答案
应该是
scanf("%lld", &d); //not scanf("%lld" &d);
