Question

c++ language

1) Create a function that prints a greeting when called with a name such as greeting ("Elona") 2) Create a function that squares a double number and returns the result as a double. 3) Create a function that takes 5 int numbers and returns the average as a float 4) Create a single function that gives a greeting, calculates the average of 5 grades but does not return a value. Hint: Use return type void and a string and 5 intas parameters. 3) Create a function that takes a string and an int and repeats a greeting the number of times specified by the int. For example, calling the function with the statement: greet_n_times ("Elena", 100): would cause a greeting "Hello Elena" to output 100 times. Hint: Put the greeting inside a for loop A n al weate a 10x10 times-table' using a function that prints out the

9 #include <iostream> 10 #include<cmath> 11 12 using namespace std; 13 14 void greeting(char name[]) 15- { 16 cout<<name; 17 } 18 19 int main() 20 - { 21 greeting("Hello Elena"); 22 return 0; 23 24 I 25 input Hello Elena

************************************************ ** ***まま oc #include <iostream> 11 using namespace std; 12 double square(double d) 14 - 15 16 return d*d;//calculating the square 17 18 int main() 19- < 20 cout<<"Square:"<<square 21 22 23 24 25 input Square: 17.64

8 #include <iostream> 9 using namespace std; 10 float average() 11 - K int a[5], sum=0; float avg; cout<<"\n Enter five numbers :"://here 5 values are taken dynamically 15 for(int i=0;i<5; i++) 16 cin>>a[i]; 18 sum = sum +a[i]; 19 avg = (float)sum/5.0; return avg; 22 23 int main() 24 { 25 cout<<"Average: <<average ; 26 return 0; 27 } 28 input Enter five numbers: 6 is Average:5.2

1 #include <iostream> 2 using namespace std; 3 void greeting grade(char name[], int g1, int g2, int g3, int g4, int g5) 4 - { float avg; cout<<"\n"<<name<<endl; avg = (float) (g1+g2+g3+g4+g5)/5;//explicit casting is used cout<<avg; ovou 13 10 int main() 11- { 12 greeting_grade ("Average",8,8,9,9,8); return 0; 14 15 16 17 10 input Average 8.4
