scanf 輸入十六進制

Here, we will declare an unsigned char variable and input different format's value like decimal format, octal format and hexadecimal format.

在這里，我們將聲明一個無符號的char變量，并輸入不同格式的值，例如十進制格式，八進制格式和十六進制格式。

• To input and print decimal value – we use "%d" format specifier

  輸入和打印十進制值–我們使用“％d”格式說明符

• To input and print octal value – we use "%o" format specifier

  輸入和打印八進制值–我們使用“％o”格式說明符

• To input and print hexadecimal value – we use "%x" format specifier

  輸入和打印十六進制值–我們使用“％x”格式說明符

Program:

程序：

#include <stdio.h>int main(void) {//data range of unsigned char is in,//1) decimal format 0 to 255//2) octal format 0 to 377//3) hexadecimal format 0 to ffunsigned char var;printf("Enter decimal value b/w 0 to 255: ");scanf("%d", &var);printf("var = %d\n", var);printf("Enter octal value b/w 0 to 377: ");scanf("%o", &var);printf("var = %o\n", var);printf("Enter hexadecimal value b/w 0 to ff: ");scanf("%x", &var);printf("var = %x\n", var);return 0; }

Output

輸出量

Enter decimal value b/w 0 to 255: 198 var = 198 Enter octal value b/w 0 to 377: 172 var = 172 Enter hexadecimal value b/w 0 to ff: f9 var = f9
