“atol” function: In C++, the predefined function “atol” is used to convert a string value into a long integer value; it passes a string literal or character array as an argument and it converts the received value into a long integer value; it takes only one parameter as an argument. If the argument value contains nonconvertible contents combined with the integer value then the values will be ignored while converting. In same way, the function will return “0” when the values can’t be able to convert into double data type. Syntax: Syntax for “atol” function is as follows: long int atol (const char* n); In the above statement, “long int” represents the return type of the function. “atol” represents the name of the function. “const char*” represents the data type of the passing argument. “n” is a string variable which is required to be converted. Example: The example for the “atol” function is as follows: //change the string literal to a long type value long n = atol ("123456 hello"); In the above line, the string literal “123456 hello” is passed as an argument to “atol” and it returns the converted value that is “123456”; here the “atol” function ignores the whitespace and the nonconvertible value “hello”.

Program Plan Intro

“atol” function:

In C++, the predefined function “atol” is used to convert a string value into a long integer value; it passes a string literal or character array as an argument and it converts the received value into a long integer value; it takes only one parameter as an argument.

If the argument value contains nonconvertible contents combined with the integer value then the values will be ignored while converting.

In same way, the function will return “0” when the values can’t be able to convert into double data type.

Syntax:

Syntax for “atol” function is as follows:

long int atol (const char* n);

In the above statement,

“long int” represents the return type of the function.

“atol” represents the name of the function.

“const char*” represents the data type of the passing argument.

“n” is a string variable which is required to be converted.

Example:

The example for the “atol” function is as follows:

//change the string literal to a long type value

long n = atol ("123456 hello");

In the above line, the string literal “123456 hello” is passed as an argument to “atol” and it returns the converted value that is “123456”; here the “atol” function ignores the whitespace and the nonconvertible value “hello”.

Consider the problem of finding a path in the grid shown below from the position S to theposition G. The agent can move on the grid horizontally and vertically, one square at atime (each step has a cost of one). No step may be made into a forbidden crossed area. Inthe case of ties, break it using up, left, right, and down.(a) Draw the search tree in a greedy search. Manhattan distance should be used as theheuristic function. That is, h(n) for any node n is the Manhattan distance from nto G. The Manhattan distance between two points is the distance in the x-directionplus the distance in the y-direction. It corresponds to the distance traveled along citystreets arranged in a grid. For example, the Manhattan distance between G and S is4. What is the path that is found by the greedy search?(b) Draw the search tree in an A∗search. Manhattan distance should be used as the
