Q1. What is printf () and scanf in C? Ans. “printf() displays output, while scanf() takes user input. They are essential C functions found in the <stdio.h> header, used for formatting and reading data.” Q2. How to make a printf function in C? Ans.Syntax:int printf(const char*...

这一句提示语的意思是说：在printf前面大概丢掉了分号（；）。c语言中的出错提示语都说的是大概。找错误时在printf前后检查有没有语法错误，而不仅仅检查是不是丢掉分号。在你发来的程序段中，printf语句前后没有发现语法错误。我判断错误是不是出现在chenge() 函数中，你没有把chenge函数的内容发来，...

or moredirectives, which are either literal characters for output or encodedconversion specificationsthat describe how to format an argument in the output. This article describes the syntax used to encode conversion specifications in the format string. For a listing of these functions, seeStream I/O...
Tinyformat parses C99 format strings to guide the formatting process --- please refer to any standard C99 printf documentation for format string syntax. In contrast to printf, tinyformat does not use the format string to decide on the type to be formatted so this does not compromise the type...
你这里报错的原因是 :do { }while(i<=1000); 这里while应该写在后边且必须加分号，你当中写的do while 循环是错误的写法，故而会报一个语法错误，另外就是你的程序逻辑 控制 还有几处错误 具体修改程序后为：include<stdio.h> int main(){ int i=100,a,b,c;printf("水仙花数为:");do...
你试试把i的定义提到上面，不要在for循环中定义 include <stdio.h> include <stdlib.h> void main(){ int i;int a[3]={1,2,3};for (i=0;i<3;i++)printf("%d",a[i]);} 不
