Using Function: Finding the maximum of three integers.

/* Fig. 5.4: fig05_04.c     Finding the maximum of three integers */  #include <stdio.h> int maximum( int x, int y, int z ); /* function prototype */  /* function main begins program execution */  int main( void )  {     int number1; /* first integer */     int number2; /* second integer */     int number3; /* third integer */     printf( "Enter three integers: " );     scanf( "%d%d%d", &number1, &number2, &number3 );     /* number1, number2 and number3 are arguments        to the maximum function call */     printf( "Maximum is: %d\n",  );     return 0; /* indicates successful termination */  } /* end main */ /* Function maximum definition */ /* x, y and z are parameters */ int maximum( int x, int y, int z ) {    int max = x; /* assume x is largest */    if ( y > max ) { /* if y is larger than max, assign y to max */       max = y;    } /* end if */
