13.sprintf and sscanf
作者:互联网
sprinf
#include<stdio.h>
int main()
{
int a = 10;
char ch = 'd';
char ch1[100] = "hello";
printf("a = %d ch = %c ch1 = %s\n", a, ch, ch1);
char ch2[100];
//格式化一个字符串,把这个字符串输出到保存的数组
sprintf(ch2, "a = %d, ch = %c ch1 = %s", a, ch, ch1);
printf("%s", ch2);
}
sscanf
#include<stdio.h>
int main()
{
int a, b, c;
printf("请输入a,b,c");
scanf("%d %d %d", &a, &b, &c);
printf("%d %d %d", a, b, c);
char ch[] = "1 2 3";
a = 0;
b = 0;
c = 0;
sscanf(ch, "%d %d %d", &a, &b, &c);
printf("%d %d %d", a, b, c);
//从ch中已制定的格式提取内容
//提取整形变量最方便
char str[] = "a = 1, b = 2, c = 3";
sscanf(str, "a = %d, b = %d, c = %d", &a, &b, &c);
printf("%d %d %d", a, b, c);
char ch2[20] = "abc mike 250";//提取字符串默认通过空格分割
char m[10], n[10], k[10];
sscanf(ch2, "%s %s %s", m, n, k);//不用地址,字符数组名就是地址
char ch2[20] = "abc, mike, 250";//提取字符串默认通过空格分割
char m[10], n[10], k[10];
sscanf(ch2, "%s, %s, %s", m, n, k);//不用地址,字符数组名就是地址,不可以用逗号作为分隔符,应该用空格
}
