Question

the answer should be in C

What is the output of the following: int whatIsThat(int * x); int main() int hold; int x[] = { 2,4,6,8); hold = whatIsThat(x); printf("%d, %d\n", x[0], hold); return 0; } int whatIsThat(int * a) { int i,sum=0; a[0] = a[O] + 6; for(i = 0; i <= 2; i++) (sum+= a[i]; a[i] = a[i] + 12; return sum; a. 20, 20 b. 20, 18 c. 18, 18 d. none of above

Answer 1

The first code's running screenshot is given below.


9 1 #include<stdio.h> 2 int whatIsThat(int* x); 3 int main() 4 { 5 int hold; 6 int m[]={2,4,6,8}; 7 hold=whatIsThat(x); 8 printf("%d,%d\n",x[], hold); return 0; 10 } 11 int what Is That(int* a) 12 { 13 int i, sum=0; 14 a[@]=a[@]+6; 15 for(i=0;i<=2; i++) 16 { 17 sum+=a[i]; 18 a[i]=a[i]+12; 19 20 return sum; 21 } ܝܟ



The output is given below.


20,18 Process exited after 5.339 seconds with return value o Press any key to continue ..



Option B is the correct answer.



2.
The running code's screenshot is given below.


4 7 1 #include<stdio.h> 2 #include<math.h> 3 typedef struct strx{ double radius; 5 double density; 6 }Sphere; double getMass (Sphere x); 8 double getVolume (Sphere x); 9 int main() 10 { 11 Sphere aluminumBall={0.1,2700}; 12 printf("The mass of the sphere is: %5.31f kilogram", getMass (aluminumBall)); 13 return 0; 14 } 15 double getMass(const Sphere x) 16 { 17 double massagetVolume(x)*x.density; 18 return mass; 19 } 20 double getVolume (const Sphere x) 21 { 22 double volume=4.0/3.0*M_PI*pow(x.radius,3); 23 return volume; 24 }



The output is given below.


The mass of the sphere is: 11.310 kilogram Process exited after 29.32 seconds with return value o Press any key to continue . .
