problems with strcat()

Hello, Im' having an issue with my program.

void inserisciPassword(char matrix[PASSWORDS][MAX])
{
    char pass[10];
    char buffer[PASSWORDS];
    int cnt=0;
    strcpy(pass,"password");
    while(cnt<100){
        sprintf(buffer,"%d",cnt);
        strcat(matrix[cnt],buffer[cnt]);
    }
    
    
}

it gives me this error: Error: Argument of type "char" is incompatible with parameter of type "const char *" in "main.cpp", Line: 21, Col: 29

Could you please help me?

strcat takes two character arrays as parameters http://www.cplusplus.com/reference/cstring/strcat/

strcat(matrix[cnt],buffer[cnt]);

Here, you are passing in a character array(matrix[cnt]) and a character(buffer[cnt]). As buffer is a character array, buffer[cnt] will give you the character at position cnt. As an aside, you have not initialized the buffer, so you are not concatenating anything to matrix[cnt].
