It is required to define the function of the factorial and the combination, and the function of the combination number to find the function of the           factorial to realize the solution, in the main () function, the function of the input           and output and call the combination number * Program input: * Program output: */#include <stdio.h > #include <stdlib.h>long FAC (int); int  Main () {    int m,n;    printf ("Please enter values for M and N:");    scanf ("%d%d", &m,&n);    if (m>=n)    {        printf ("Combined number C (m,n) is:%d", FAC (m)/(FAC (n) *FAC (m-n)));}    } Long FAC (int n)  //is used to find the factorial of n {    int i;    Long S=1;    for (i=1;i<=n;i++)    {        s*=i;    }    return s;}
