Problem #3 - Search a string. Write a program which counts the number of a particular character found in a string. For example, in the string "double down" there are two 'd' characters. Use a loop to go through the string from beginning to end and compare each character in the string with the character to find. If the character is found, increment a count. Print out the string and the number found. See the screen shot below. The string is "Find the letter i in this string." The character to find and count is 'i'. Name the file "string_search.c". The typical way to go through a string from beginning to end is using a while loop. The test in the loop checks if the current element in the loop is a NULL character. If a NULL is found, stop looping since the end of the string has been found. For example, i- 0; while(str[i] !- '\0') { Of course, i must be incremented to go through the string each time through the loop. String: Find the letter i in this string. Count: 5 execution time : 0.081 s Process returned 0 (0x0) Press any key to continue.

Loops are the elements of programming in which a part of code is repeated a particular number of times. Loop executes the series of statements many times till the conditional statement becomes false.

Any task which is repeated more than one time is called a loop. Basically, loops can be divided into three types as while, do-while and for loop. There are so many programming languages like C, C++, JAVA, PYTHON, and many more where looping statements ca…

Loop is a feature in the programming language. It helps us to execute a set of instructions regularly. The block of code executes until some conditions provided within that Loop are true.
