C++ Char errors

So I'm trying to take the second to first character from Expresie which is a char array and copy it into a char variable, and then use the strcat function to place that variable at the end of another char array Stiva. this is the code: 

int SHIFT(char Expresie[], char Stiva[], int x)
{
        char a=Expresie[0];
        strcat(Stiva,a);

And this is how they are defined in main: 

    int main()
{
    char Expresie[100];
    char Stiva[100];

The problem is that when i run it it says : invalid conversion from 'char' to 'const char*'

strcat appends strings, not characters - it wants a pointer to the first character of a "C string", not a single char.

The simplest way to do this is to add the character directly at the end yourself (assuming that there is room, of course):

int SHIFT(char Expresie[], char Stiva[], int x)
{
    char a=Expresie[0];
    size_t length = strlen(Stiva);
    Stiva[length] = a;
    Stiva[length+1] = 0;
    // ...
