Snippet Name: Convert strings to integers
Keywords: String, Integer, Loops
Description(Optional): A messy bit of code used by me to convert strings to integers

Code:

#include <math.h>
#include <string.h>

Code:

unsigned long StrToInt(std::string str){
unsigned long rint = NULL;
unsigned long size = str.size();
unsigned long fi[sizeof(str)];
unsigned long mul;

for( int i = 0; i != size; i++){
        if( str.at(i) == '0' ) fi[i] = 0;
	if( str.at(i) == '1' ) fi[i] = 1;
	if( str.at(i) == '2' ) fi[i] = 2;
	if( str.at(i) == '3' ) fi[i] = 3;
	if( str.at(i) == '4' ) fi[i] = 4;
	if( str.at(i) == '5' ) fi[i] = 5;
	if( str.at(i) == '6' ) fi[i] = 6;
	if( str.at(i) == '7' ) fi[i] = 7;
	if( str.at(i) == '8' ) fi[i] = 8;
	if( str.at(i) == '9' ) fi[i] = 9;
}

for(int i = 0; i != str.size() ; i++){
	mul = (1 * pow(10, (double)size-1));
	size--;
	rint += ( mul * fi[i]);
}
return rint;
}

Use

Code:

int i = (int) StrToInt("5192491");

i wil now hold 5192491, as an integer variable

Hell: Or you just use atoi(str.c_str());

Your code to convert alpha to numeric is a little larger than it needs to be..Atoi isn't always a reliable routine to use so a smaller alternative could be to use

Snippet: Smaller Alpha To Numeric ( atoi )
Keywords: String, Numeric, Alpha, ATOI, ITOA

[php]
#define isnumeric(a) ( ( a >='0' && a <='9' ) )
#define isalpha(a) !isnumeric(a)
#define tonum(a) ( ( a - '0' ) )

long strtonum( char *buffer )
{
long tmpNum;
tmpNum = 0;

if ( !isnumeric(*buffer) ) return -1;

while ( isnumeric(*buffer) )
{
tmpNum = ( tmpNum * 10 ) + tonum( *buffer );
(buffer)++;
}
return tmpNum;
}
[/php]

Usage: retval = strtonum( "1234" )
retval=1234
