Answer:
<u>C program to find the sum of the series( 1/2 + 2/3 + ... + i/i+1)</u>
#include <stdio.h>
double m(int i);//function declaration  
//driver function
int main() {
int i;
printf("Enter number of item in the series-\n");//Taking input from user
scanf("%d",&i);
double a= m(i);//Calling function
printf("sum=%lf",a);
return 0;
}
double m(int i)//Defining function
{
double j,k;
double sum=0;
for(j=1;j<i+1;j++)//Loop for the sum
{
k=j+1;
sum=sum+(j/k);
}
return sum;
}
<u>Output:</u>
Enter number of item in the series-5
sum=3.550000
 
        
             
        
        
        
Answer:
The result of the following code will be 9
Explanation:
There are several operators used in Python to do mathematical calculations. 
** operator is used for exponents. 
i.e.
a ** b mathematically means a^b
Here in the given code
3 is assigned to numA and 2 is assigned to numB
Result will be equal to 3^2
Hence,
The result of the following code will be 9

Explanation:
While time-consuming or prone to errors mechanical adjustments to both the referential, databases could be configured with four measures to engine violations. The restricted action causes the insert, update, and removes to only be denied. Set Null to NULL sets the invalid external key, whereas Set Default to a specific core consideration specified in SQL sets a default foreign key. Its Cascade operation spreads the main changes in external keys.
