(C++) World Population Growth Rate For this exercise, research world population growth issues online. Be sure to investigate various view points. Get estimates for the current world population and its growth rate ( the percentage by which it is likely to increase this year). Write a program that calculates world population growth each year for the next 75 years, using the simplifying assumption that the current growth rate will stay constant. Print the results in a table. – The first column should display the year from year 1 to year 75. – The second column should display the anticipated world population at the end of that year. – The third column should display the numerical increase in the world population that would occur that year. Using the results, determine the year in which the population would be double what it is today, if this year’s growth rate were to persist. Must use setprecision(decimal point) and output what year the population doubles regardless on user input.

Introduction:

Population growth is a critical issue that requires careful understanding and analysis. In order to explore the world population growth rate, this exercise requires researching various viewpoints and estimating the current world population, as well as the growth rate. This information will be used to develop a program that calculates the world population growth for the next 75 years, assuming a constant growth rate. The program will also determine the year in which the population would double if the current growth rate persists.

Methodology:

To begin, extensive research needs to be conducted to gather accurate data on the current world population and its growth rate. It is crucial to source information from reliable and reputable sources to ensure accuracy and reliability. Generally, global organizations such as the United Nations, World Bank, and World Health Organization provide valuable data on population statistics.

Once the necessary data is collected, a C++ program can be developed. The program will be designed to calculate the world population growth for the next 75 years, assuming a constant growth rate. The output will be displayed in a table format with three columns: the year, the anticipated world population at the end of that year, and the numerical increase in the world population for that year.

To determine the year in which the population would double, an additional analysis needs to be performed. The program will continue calculating the population growth for each year until the population reaches twice its current value. At that point, the program will output the specific year in which the population doubles.

In terms of programming techniques, the program will utilize setprecision(decimal point) to ensure that the numerical output is displayed with the appropriate level of precision. This feature can be applied to ensure the appropriate number of decimal places are included in the output, providing a clear and accurate representation of the calculated values.

Results:

Once the program is executed, it will generate a clear table displaying the year, the anticipated world population at the end of that year, and the numerical increase in the world population for each year. This information will provide important insights into the projected global population growth over the next 75 years.

Furthermore, the program will identify the specific year in which the population is estimated to double based on the assumption of a persisting growth rate. This result will allow for a deeper understanding of the potential future population trends and can assist in strategic planning and decision-making to address population-related challenges.

Conclusion:

By conducting thorough research and developing a C++ program that calculates world population growth, we can gain valuable insights into future population trends. This exercise provides an opportunity to analyze the world population growth rate assumptions and understand the potential impacts on society and the environment. The program’s results, such as the table presenting population growth over the next 75 years and the year in which the population is projected to double, offer essential information for policymakers, researchers, and individuals interested in addressing global population issues.
