c语言scanf输入字符

We have to read tree values: integer, float and then character using only one scanf() function and then print all values in separate lines.

我们只需要使用一个scanf()函数读取树值：整数，浮点数和字符，然后将所有值打印在单独的行中。

**Example:**

**例：**

Input:
        Input integer, float and character values: 10 2.34 X
    
        Output:
        Integer value: 10
        Float value: 2.340000
        Character value: X

Before moving to the program, please consider the scanf() statement,

移至该程序之前，请考虑scanf()语句，

scanf ("%d%f%*c%c", &ivalue, &fvalue, &cvalue);

Here, %\*c is used to skip the character to store character input to the character variable, almost all time, character variable’s value will not be set by the given value because of the **"ENTER"** or **"SPACE"** provided after the float value, thus, to set the given value, we need to skip it.

此处， ％\* c用于跳过字符以将输入的字符存储到字符变量中，几乎所有时间，由于在浮点值之后提供**“ ENTER”**或**“ SPACE”** ，因此将不会通过给定值设置字符变量的值，因此，要设置给定值，我们需要跳过它。

**Program:**

**程序：**

# include <stdio.h>
    
    int main ()
    {
        
    	int ivalue;
    	float fvalue;
    	char cvalue;
    
    	//input 
    	printf("Input integer, float and character values: ");
    	scanf ("%d%f%*c%c", &ivalue, &fvalue, &cvalue);
    
    	//print 
    	printf ("Integer value: %d\n", ivalue) ;
    	printf ("Float value: %f\n", fvalue) ;
    	printf ("Character value: %c\n", cvalue) ;
    
    	return 0;
    }

**Output**

**输出量**

Input integer, float and character values: 10 2.34 X
    Integer value: 10
    Float value: 2.340000
    Character value: X
