Description:Imagine you're developing a text processing tool that facilitates replacing specific characters in a primary string. Your task is to write a program that accomplishes this efficiently.Input:The first line should prompt the user to enter the primary string ('PS').The second line should ask for the character to be replaced ('c').The third line should request the replacement string ('s').Output:Display the resulting string after replacing each occurrence of 'c' with 's'.

The first line should prompt the user to enter the primary string ('PS').The second line should ask for the character to be replaced ('c').The third line should request the replacement string ('s').

Write a program to return a string from a given string s where all occurrences of the first char of the string except the first occurrence have been changed to '$'.Input Format:The number of test cases. For each testcase there will be a single line of input as explained following.The single line consists of a string.Output Format:Resultant stringSample Input:1"restart"Sample Output:"resta$t"

Write a C program to read a sentence and replace lowercase characters with uppercase and vice versa.

Your goal is to write a program that will ask the user for a long string and then a substring of that long string. The program then will report information on the long string and the substring. Finally it will prompt the user for a replacement string and show what the long string would be with the substring replaced by the replacement string. Each of the lines below can be produced by using one or more String methods - look to the String method slides on the course website to help you with this project.A few sample transcripts of your code at work are below - remember that your code should end with a newline as in the textbook examples and should produce these transcripts exactly if given the same input. Portions in bold indicate where the user has input a value.One run of your program might look like this:Enter a long string: The quick brown fox jumped over the lazy dogEnter a substring: jumpedLength of your string: 44Length of your substring: 6Starting position of your substring: 20String before your substring: The quick brown fox String after your substring: over the lazy dogEnter a position between 0 and 43: 18The character at position 18 is xEnter a replacement string: leapedYour new string is: The quick brown fox leaped over the lazy dogGoodbye!A second run with different user input might look like this:Enter a long string: Friends, Romans, countrymen, lend me your earsEnter a substring: tryLength of your string: 46Length of your substring: 3Starting position of your substring: 21String before your substring: Friends, Romans, counString after your substring: men, lend me your earsEnter a position between 0 and 45: 21The character at position 21 is tEnter a replacement string: catchYour new string is: Friends, Romans, councatchmen, lend me your earsGoodbye!
