convert string in to integer

[haniya ali]

struct time
{ int t;
	int h,m,s;	
};

int main()
{
	time t;
	int totalsecond;
	char A[10],B[10];
	cout<<"Enter the time Format [12:59:59] = ";
	cin.getline(A,10);
	int i=0,j=0;
	while(A[i]!=':')
	{
		B[j]=A[i];
		i++;
		j++;
	}
	t.h=atoi(B);
	i++;
	j=0;
	while(A[i]!=':')
	{
		B[j]=A[i];
		i++;
		j++;
	}
	t.m=atoi(B);
	i++;
	j=0;
	while(A[i]!='\0')
	{
		B[j]=A[i];
		i++;
		j++;
	}
	t.s=atoi(B);
	
	totalsecond=(t.h*3600)+(t.m*60)+t.s;
	cout<<"\n\nTotal Seconds are = "<<totalsecond;
	
	cout<<endl;
	getch();
	
}

it gives error at line no 12. any one resolve it?

What error are you getting?

[haniya ali]

i am getting error at line no 8. t undeclared first use this function etc

[weaknessforcats]

Before you said it was line 12. Do you mean line 8 on your first post or line 12?

If it turns out to be line 12 have you included <iostream>?

[haniya ali]

yeah, i included it was on line 12

Try

std::cin.getline

[Sherin]

Try This Code

#include <iostream>
#include <string>

int main() {

	std::string s = "10";

	try
	{
		int i = std::stoi(s);
		std::cout << i << '\n';
	}
	catch (std::invalid_argument const &e)
	{
		std::cout << "Bad input: std::invalid_argument thrown" << '\n';
	}
	catch (std::out_of_range const &e)
	{
		std::cout << "Integer overflow: std::out_of_range thrown" << '\n';
	}

	return 0;
}
