[英]How can I reduce the number of arguments with this "printf" function? Should I be using something other than "printf"?
我遇到了一個我一直在嘗試解決的問題。 我理解 printf 和 puts 之間的區別,所以我認為 printf 是進入這里的正確方法。
但是,我收到一條錯誤消息:
“警告:格式參數過多 [-Wformat-extra-args]
printf("%s", "The sum of %d", first , " and %d", second, " is %d", first + second);
^"
是否有更好的功能來打印我需要的輸出,或者可能有一種不同的方式來格式化這個輸出?
#include <stdio.h>
void main()
{
int first, second;
int answer = 1;
while (answer == 1)
{
puts("Please enter the first integer ==> ");
scanf("%d", &first);
puts("Please enter the second integer ==> ");
scanf("%d", &second);
printf("%s", "The sum of %d", first , " and %d", second, " is %d", first + second);
puts("Would you like to add two more integers?\n"
"(1 for yes) ==> ");
scanf("%d", &answer);
}
}
您的格式字符串必須是printf
的第一個參數,您的輸入必須是以下參數。 例如:
printf("The sum of %d and %d is %d", first, second, first + second);
