大佬们，这道题怎么同时用fgets和atoi函数解决啊

因为visual studio用不了gets，拜托了

用atoi阿...

取数字会不会,有string类型阿。。

#include <string>
#include <iostream>
using namespace std;
#pragma warning(disable:4996)
int  main()
{
	string x = "a123b456";
	string s;
	int j = 0;
	for (int i = 0; i < x.size(); i++) {
		if (x.at(i) >= '0' && x.at(i) <= '9') {
			s.push_back(x.at(i));
		}
		else {
			printf("%s\n", s.data());
			j++;
			s.clear();
			continue;
		}
			
	}
	printf("%s\n", s.data());
	printf("%d", j);
	return 0;
}

C++有更正宗的输入输出iostream呀。

#include <iostream>

using namespace std;

int  main()
{
    cout << "Please enter a line of text with digits and nun-digit characters: " << endl;
	string buffer;
	getline(cin, buffer);
	
	int numbers[100];
	int count = 0;
	
	for (int i = 0; i < buffer.length(); ++i)
	{
		if (buffer[i] >= '0' && buffer[i] <= '9')
		{
			int n = 0;
			for (; i < buffer.length() && buffer[i] >= '0' && buffer[i] <= '9'; ++i)
			{
			    n = n * 10 + (buffer[i] - '0');
			}
			numbers[count++] = n;
		}
	}
	
	cout << "The numbers embedded in the line are: " << endl;
	for (int i = 0; i < count; ++i)
	{
	    cout << numbers[i] << endl;
	}
	
	return 0;
}

// Output
Please enter a line of text with digits and nun-digit characters:                                  
abc123cde345 678$%^9^&*10a100mmm88great1

345

10

改成了用fgets和atoi：

#include <iostream>
#include <stdlib.h>
#include <string.h>

using namespace std;
int  main()
{
    cout << "Please enter a line of text with digits and nun-digit characters: " << endl;
	char buffer[1024];
	fgets(buffer, 1024, stdin);
	
	int numbers[100];
	int count = 0;
	
	for (int i = 0; i < strlen(buffer); ++i)
	{
		if (buffer[i] >= '0' && buffer[i] <= '9')
		{
			int n = atoi(buffer + i);
			
			i += to_string(n).length();
			numbers[count++] = n;
		}
	}
	
	cout << "The numbers embedded in the line are: " << endl;
	for (int i = 0; i < count; ++i)
	{
	    cout << numbers[i] << endl;
	}
	
	return 0;
}

// Output
Please enter a line of text with digits and nun-digit characters:
