Exercise F5 Assume given the following definition of function process: void process(int vnum, int \& rnum1, int \& rnum2) \{ vnum=vnum+5rnum1=rnum1+10;rnum2=vnum+rnum1 \} And that local variables are defined in function main as follows: intnum1=6,num2=9,num3=12; Indicate whether each of the following calls of function process is valid or invalid. Also give the reason why a call is invalid. a. process(15, num 2, num3 ); b. process(21, num 1+3, num 2 ); c. process( num3, num1, num2 ); d. process( num1, 10, num3 ); e. process( 3 , num1,25); f. process( num1, num2, num3 3+4) g. process( num2, num1 ); h. process( num 1+3, num2, num3); i. process(5, num3 ); j. process( num1, num1, num3 )
