sprintf(newstring, "%s %d", str, num);
Reply:im not sure if this works in C, but there is a function called itoa(). to use it:





char str[15] = "outref";


char charnum[10];


int num = 100;





itoa(num, charnum, 10);


strcat(str, charnum);


//now str = outref100
Reply:You can do this with sprintf().





int i = 5;


char str[10];





sprintf(str, "blah %i", i); // str is now "blah 5"
