Question

How would you append an integer to a char* in c++?

Answer 1

First convert the int to a char* using sprintf():

char integer_string[32]; int integer = 1234;  sprintf(integer_string, '%d', integer); 

Then to append it to your other char*, use strcat():

char other_string[64] = 'Integer: '; // make sure you allocate enough space to append the other string  strcat(other_string, integer_string); // other_string now contains 'Integer: 1234'
