有人可以告诉我我的代码有什么问题以及为什么它会产生这个输出。
代码：
int main(){
unsigned num;
char response;
do{
printf("Please enter a positive integer greater than 1 and less than 2000: ");
scanf("%d", &num);
if (num > 1 && num < 2000){
printf("All the prime factors of %d are given below: \n", num);
printPrimeFactors(num);
printf("\n\nThe distinct prime factors of %d are given below: \n", num);
printDistinctPrimeFactors(num);
}
else{
printf("\nSorry that number does not fall between 1 and 2000.\n");
}
printf("\n\nDo you want to try another number? Say Y(es) or N(o): ");
getchar();
response = getchar();
}
while(response == 'Y' || response == 'y'); // if response is Y or y then program runs again
printf("Thank you for using my program. Good Bye!\n\n"); //if not Y or y, program terminates
return 0;
}
输出：
Please enter a positive integer greater than 1 and less than 2000: 1600
All the prime factors of 1600 are given below:
2 2 2 2 2 2 5 5
The distinct prime factors of 1600 are given below:
2 5
Do you want to try another number? Say Y(es) or N(o): yes
