hi im new to c and mikroc,
im having troubles with joining two strings, can some one help\teach me how it is done?

heres my code:
Code: 
d=12;
IntToStr(d, dtemp);
txt=strcat("0",dtemp);
LCD_Out(2, 1,txt );
i cant compile the code what is wrong in my code?
also im trying to print it on the lcd like this:012

- - - Updated - - -

i change it in to this

Code: 
d=12;
m=0
IntToStr(d, dtemp);
IntToStr(m, mtemp);

strcat(dtemp, mtemp);
            LCD_Out(2, 1, dtemp);
it displays wierd symbols

if you look at the specification of strcat()
https://www.cplusplus.com/reference/cstring/strcat/

i.e
Code: 
char * strcat ( char * destination, const char * source );
you will see the first parameter is the destination and the source is concatenated onto it

in your code
Code: 
txt=strcat("0",dtemp);
the first parameter "0" is a string constant and will either give a compiler error or a run time such as a segmentation fault
make the destination a char array and it will work, e.g.
Code: 
char txt[50]="0";
strcat(txt,dtemp);
 

i found a new solution but still something is wrong, it has spaces in between them
how can i remove these spaces?

heres the code

Code: 
d=12;
m=0;
IntToStr(d, dtemp);
IntToStr(m, mtemp);

txt[12]=strcat(mtemp,dtemp); 
            LCD_Out(2, 1, txt[12]);
 

Use the Ltrim function.

char mtemp[7+7]; // long enough to accomodate two 7-char arrays
char dtemp[7];
 
// .....
 
d = 12; // any signed (!) integer number 
m = 0;  // ditto  
 
IntToStr(d, dtemp);
IntToStr(m, mtemp);
LCD_Out(2, 1, strcat(Ltrim(mtemp), Ltrim(dtemp));
