【笔记】关于sscanf与sprintf的用法

sscanf与sprintf用法
sscanf是将str以"%d"的格式写到n中(从左至右)

代码

​
//#include<bits/stdc++.h>  
#include<cstdio>
#include<iostream>
#include<cstring>

using namespace std;


int main()
{
	char str[100]="11111";
	int n;
	sscanf(str,"%d",&n);
	cout<<n;
}

​

sprintf是把n以"%d"的格式写入到str当中(从右至左执行)

代码

//#include<bits/stdc++.h>  
#include<cstdio>
#include<iostream>
#include<cstring>

using namespace std;


int main()
{
	char str[100];
	int n=11111;
	sprintf(str,"%d",n);
	cout<<str;
}
