scanf()的一些用法救命。

#include <stdio.h>

int main( void )
{
    int i1;//from  w w  w .j  a  va  2 s .com
    int i2;
    long l1;

    double d1;
    char buf1[80];
    char buf2[80];

    /* Using the l modifier to enter long integers and doubles.*/

    puts("Enter an integer and a floating point number.");
    scanf("%ld %lf", &l1, &d1);
    printf("/nYou entered %ld and %lf./n",l1, d1);
    puts("The scanf() format string used the l modifier to store");
    puts("your input in a type long and a type double./n");

    fflush(stdin);

    /* Use field width to split input. */

    puts("Enter a 5 digit integer (for example, 54321).");
    scanf("%2d%3d", &i1, &i2);

    printf("/nYou entered %d and %d./n", i1, i2);

    fflush(stdin);

    /* Using an excluded space to split a line of input into */
    /* two strings at the space. */

    puts("Enter your first and last names separated by a space.");
    scanf("%[^ ]%s", buf1, buf2);
    printf("/nYour first name is %s/n", buf1);
    printf("Your last name is %s/n", buf2);

    return 0;
