5.1.3 Agricultural effects and population limits.5.1.2 Effects of historical oil price rises.3.6.1 Anticipated production by major agencies.Following a collapse in oil demand at the outset of the COVID-19 pandemic and a price war between Saudi Arabia and Russia, a number of organizations have put forward predictions of a peak in the next 10 to 15 years. A decade later world oil production rose to hit a new high in 2018, as developments in extraction technology enabled an expansion of U.S. Predictions of future oil production made in 20 stated either that the peak had already occurred, that oil production was on the cusp of the peak, or that it would occur soon. These predictions are dependent on future economic trends, technological developments, and efforts by societies and governments to moderate climate change. Hubbert's original predictions for world peak oil production proved premature and, as of 2021, forecasts of the year of peak oil range from 2019 to 2040. King Hubbert is often credited with introducing the notion in a 1956 paper which presented a formal theory and predicted U.S. Numerous predictions of the timing of peak oil have been made over the past century before being falsified by subsequent growth in the rate of petroleum extraction. A secular decline in oil extraction could be caused both by depletion of accessible reserves and by reductions in demand that reduce the price relative to the cost of extraction, as might be induced to reduce carbon emissions. It is related to the distinct concept of oil depletion while global petroleum reserves are finite, the limiting factor is not whether the oil exists but whether it can be extracted economically at a given price. Peak oil is the moment at which extraction of petroleum reaches a rate greater than that at any time in the past and starts to permanently decrease. Printf(' Reached to the end of file.Hubbert's upper-bound prediction for US crude oil production (1956) in red, and actual Lower 48 states production through to 2014 in green The function feof() is checking again that pointer has reached to the end of file or not. When integer variable c is not equal to EOF, it will read the file. In the above program, In the above program, file is opened by using fopen(). Printf(' Reached to the end of file.') Here is an example of feof() in C language, Here is the syntax of feof() in C language, int feof(FILE *stream) It returns non-zero value if successful otherwise, zero.

The function feof() is used to check the end of file after EOF. The function getc() is reading the characters from the file. In the above program, file is opened by using fopen(). LetвЂ™s say we have вЂњnew.txtвЂќ file with the following content в€’ This is demo! Here is an example of getc() in C language,

Here is the syntax of getc() in C language, int getc(FILE *stream) It reads a single character from the input and return an integer value. LetвЂ™s say we have вЂњnew.txtвЂќ file with the following content. The function getc() returns EOF, on success.
