In this tutorial we will learn aboutPrintf() and Scanf() functions in Embedded C Programming. Theprintf()andscanf()function are theInput and Output functionalso called asI/O functionsused to get and receive the data in C language. prinf() function works to print the specified output from p...
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*...
scanf() 把输入的字符串转换成整数、浮点数、字符或字符串,而 printf() 正好与它相反,把整数、浮点数、字符和字符串转换成显示在屏幕上的文本。 scanf() 和printf() 类似,也使用格式字符串和参数列表。scanf() 中的格式字符串表明字符输入流的目标数据类型。两个函数主要的区别在参数列表中。printf() 函数使用...
