[PIC] MicroC Concatenate and conversion

[yanal]

if I have a char array like : getRequest[18] ,, How i can specify some digits of this array to a variable like : ID_1st;

Example : getReqest[1]=1; getRequest[3]=5 ;
:fight:
i want to store this two digits to variable that show the ID_1st is :15;

what is the type of ID_1st and how to Concatenate digits within it !!


I wish you have a nice day friends

Be sure not to confuse digit values like 1 with character codes like '1'.

Presumed you have two digit values and want to combine it to a single binary number, you simply multiply the first digit with 10

ID_1st  = 10* getReqest[1] +  getReqest[3];

Strings representing a digital number can be decoded with atoi() or sscanf().

Strings representing a digital number can be decoded with atoi() or sscanf().

so if i have : getRequest[7]='1' ; and getRequest[8]='3' ;
i should define int variable like int x and use atoi() function ~~

int x;
char c;
char c2;

c=getRequest[7];
c2=getRequest[8];
x=10*atoi(c)+atoi(c2) ;

thats Correct or not ??

oops yes you are right i have character codes .. gerRequest[7]='1' ; getRequest[8]='5'

so how i can convert them to int or how i can put them to variable like long x = 15 ???

 

[pic.programmer]

Try

atoi() or atol()

after terminating the arry with null character.

 

[yanal]

could you please give me an example !!
if i have char getRequest[20];
and getRequest[7]='1';
and getRequest[8]='2';

how can i store this two as not character at Long variable as L_nm ; to be L_nm=12;

 

[pic.programmer]

mikroC and mikroBasic PRO have atoi() and atol() functions. Search in Help File's Index. You will get example on how to use. Terminate the array with null character and use Ltrim() and Rtrim() and then atoi().

Example

unsigned int myInt = 0;

void main() {

     while(1) {
             getRequest[9] = '\0';
             Ltrim(getRequest);
             Rtrim(getRequest();
             myInt = atoi(getRequest); 
     }
}

 

[FvM]

If it's no problem to modify the input string

get_request[9]=0;
L_nm = atoi(&get_request[7]);

otherwise

char temp[3];
strncpy(temp, &get_request[7], 2);
L_nm = atoi(temp);

Ltrim() and Rtrim() are no standard C functions.(And not required for the present problem anyway).

I did it by this way you are so helpful .. regards

void x_array(){
int i;
 char x[1];
 x[0]=getRequest[7];
 x[1]='\0';
 i=atoi(x);
 portb=i;
 }

 

[pic.programmer]

You should then use

char x[2];
