According to a study, the approximate level of intelligence of a person can be calculated using the following formula:

i = 2 + ( y + 0.5x )

Write a C program that will produce a table of values of i, y and x, where y varies from 1 to 6, and, for each value of y, x varies from 5.5 to 12.5 in steps 0.5.

### Logic To understanding the problem statement

**1.** Problem statement snippet: “..y varies from 1 to 6”. That means, we can accomplish it using a looping statement. So we can take a for loop and initialize variable y to 1 and iterate the for loop until y is less than or equal to 6.

**2.** Problem statement snippet: “..for each value of y, x varies from”. That means we should write a nested for loop here.

**3.** Problem statement snippet: “..for each value of y, x varies from 5.5 to 12.5 in steps 0.5”. That means, we need to write a nested for loop and initialize x value to 5.5 and iterate through the for loop until x value is less than or equal to 12.5 And for each iteration of the inner for loop we need to increment the value of x by 0.5

### Source Code: C Program To Calculate Approximate Level of Intelligence of a Person

#include<stdio.h> int main() { int y, count = 1; float i, x; for(y = 1; y <= 6; y++) { for(x = 5.5; x <= 12.5; x += 0.5) { i = 2 + (y + 0.5 * x); printf("%d. i = %0.2f,\t x = %0.2f,\t y = %d\n", count++,i, x, y); } } return 0; }

**Note:** Inner for loop executes from 5.5 to 12.5 with a 0.5 step increment for each loop. So its 15 iterations. Outer for loop executes 6 times. So total iterations equals 15 x 6 = 90 times. So 90 values will be printed to the console window.
