For C
I need help with making a program that estimates pi using the equation:
pi = 4 * (1-1/3+1/5-1/7+1/9-1/11+1/13+.........)
If the input is 4 then the program should compute:
4*(1-1/3+1/5-1/7)
If the input is 9 the program should compute the value:
4*(1-1/3+1/5-1/7+1/9-1/11+1/13-1/15+1/17). The output of the program a line of the form:
Estimate is X.
Where X is the extimte of pi based on the specified number of terms, with 6 digits of precision, for e xample if the input is 5 then the outpu is:
Estimate is 3.339683
Transcribed Image Text:Hints:
• Variables are provided for number of terms and TI
estimate
• Input and output are already taken care of for you
• Use double Variables to store the value of each term and
the sum of the series
• Start series sum calculation with a loop that counts from
1 to n, where n is the number of terms
• Plan the loop by determining how the correct term can
be computed on each iteration of the loop. For example,
how can you compute the correct denominator (1, 3, 5,
7, ..) for each term? How can you determine the correct
sign (alternating positive and negative) for each term?
• You may want to have multiple loop variables.
• Don't use integer division!
