I thought of using either case statements or if to figure out how many digits the number is and then convert it to an char array with extra 0's for printing, but I can't help but think there may be a way to do this with the printf format syntax that is eluding me.推荐答案printf("%05d", zipCode); 0 表示要填充的内容, 5 表示整数的宽度.The 0 indicates what you are padding with and the 5 shows the width of the integer number.示例1:如果使用%02d" (对日期有用),则只会在一"列中填充数字零.例如 06 而不是 6 .Example 1: If you use "%02d" (useful for dates) this would only pad zeros for numbers in the ones column. E.g., 06 instead of 6.示例2:%03d" 将在one列中填充2个零以表示一个数字,在tens列中填充1个零以表示一个数字.例如,将7号填充到 007 中,将17号填充到 017 中.Example 2: "%03d" would pad 2 zeros for one number in the ones column and pad 1 zero for a number in the tens column. E.g., number 7 padded to 007 and number 17 padded to 017. 这篇关于在C中打印前导0的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持! 上岸,阿里云!
