Q3. What is printf syntax? Ans. “Theprintf()function in C is used to display text and data on the console. It uses a format string and an argument list for customized output.”
Here is the syntax of sprintf() in C language, int sprintf(char *str, const char *string,...); Here is an example of sprintf() in C language, Example Live Demo #include<stdio.h> int main() { char buf[20]; int x = 15, y = 25, z; z = x + y; sprintf(buf, "Sum of ...
It is defined in the cstdio header file. Example #include <cstdio> int main() { int age = 23; // print a string literal printf("My age is "); // print an int variable printf("%d", age); return 0; } // Output: My age is 23 Run Code printf() Syntax The syntax of ...
Syntax Following is the syntax of printf() in C and C++ language: printf("string and format specifier", variable_name); Here, String: Any text/message to print on console. Format Specifier: According to the variable datatype, use format specifiers like %d, %s etc. variable_name: Any na...
Syntax of scanf() function: scanf("format string",arguments); Example 1: use printf() and scanf() functions to add two input numbers In the following example, we are calculating the sum of two user entered numbers. Program prints message on console to enter the numbers usingprintf(). The...

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...
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，...
