Thread: make one string from 2 strings.

hello
i managed to parse the parts that i need from this string:

Code:

"GET /send.htm?Text=START+00500+11611 HTTP/1.1"

with this pair of code ( with help of this forum ):

Code:

char Text[80] = {0};
	char * line = "GET /send.htm?Text=START+00500+11611 HTTP/1.1";
	char *s,*t;
	char bt_msg[20] = {0};

	if(s = strchr(line, '+')) 
	{
		if(t = strchr(s, ' '))
			strncpy(Text, s+1, t-s);
	}


	char *xcoord=strtok(Text,"+"), *ycoord=strtok(NULL,"+");
	printf("x-coord:%s\n", xcoord);
	printf("y-coord:%s\n", ycoord);
}

so basically:
the output will be:

Code:

x-coord: 00500
y-coord: 11611

i need to assemble a payload that follows the following structure:

Code:

"X=00500Y=11611"

than means the first five digits represent the x-coord and the 2nd five digits represent y-coord.
i need to save assemble this payload from those coordinates and put in a variable so i can use it later on.may be save it as bt_msg. how could i do it?
thanks
