C program to print four powers of numbers 1 to 9 using nested for loop
Nested loops consist of one loop placed inside another loop.An example of a nested for loop is as follows −for (initialization; condition; operation){ for (initialization; condition; operation){ statement; } statement; }In this example, the inner loop runs through its full range of iterations for each single iteration of the outer loop.ExampleFollowing is the C program to print the table of first four powers of numbers 1 to 9 by using nested for loop −#include void main(){ int i, j, k, temp, I=1; printf("I\tI^2\tI^3\tI^4 "); printf("--------------------------------"); for ( i = ...
Read MoreC program to perform operations on two halves’ in a single array
ProblemWrite a program to accept a one-dimensional array of N elements and split into two halves. Later on, sort the first half in an ascending order and the second half into descending order.SolutionThe solution to perform the two operations on two halves’ in a single array in C programming language is explained below −The logic used to sort the first half in an ascending order is as follows −for (i=0; i
Read MoreC program to interchange the diagonal elements in given matrix
ProblemWe need to write a code to interchange the main diagonal elements with the secondary diagonal elements. The size of the matrix is given at runtime.If the size of matrix m and n values are not equal, then it prints that the given matrix is not a square.Only a square matrix can interchange the main diagonal elements and can interchange with the secondary diagonal elements.SolutionThe solution to write a C program to interchange the diagonal elements in given matrix is as follows −The logic to interchange the diagonal elements is explained below −for (i=0;i
Read MoreC program to sort all columns and rows of matrix
ProblemWrite a code to sort all the rows of matrix in an ascending order and all columns in the descending order. The size of matrix and elements of matrix are given by user at runtime.SolutionThe solution to sort all the rows of matrix in an ascending order and all columns in the descending order in the C programming language is explained below −The logic used to sort the rows in an ascending order is as follows −for (i=0;i
Read MoreC program for DFA accepting all strings over w ∈(a,b)* containing “aba” as a substring
ProblemDesign a DFA for the language L={w1abaw2 | w1, w2 Є(a, b)*}, which means the DFA accepts all strings which contain “aba” as a substring.SolutionThe strings that are accepted by language L= {aba, aabaa, aabab, babab, ababa, …….}Step 1 − Transition diagram for minimal string (starting string) −If w1 and w2 are null then the string it generates is “aba” because w1, w2 ε(a, b)*q0 is the initial state and q3 is the final state.Step 2 − The final DFA for the given language is as follows −Explanationqo is the initial state q0 on ‘a’ goes to q1 and on ...
Read MoreC Program to construct DFA accepting odd numbers of 0s and 1s
Construct deterministic finite automata (DFA) for the language L = { w : w has odd number of 0’s and w has odd number of 1’s}, over the alphabet Σ = {0, 1}.Example0111, 010101, 01110011 is an accepted string, because those strings have an odd number of 0’s and an odd number of 1’s.For the given language we will need four states to draw the main DFA which will read odd no. of 0s and 1s. We can also draw it by merging the two DFAs in which one will accept only an odd number of 0s and one accepts ...
Read MoreC Program to build DFA accepting the languages ending with “01”
ProblemDesign deterministic finite automata (DFA) with ∑ = {0, 1} that accepts the languages ending with “01” over the characters {0, 1}.SolutionThe strings that are generated for a given language are as follows −L={01, 001, 101, 110001, 1001, ……….}The minimum length of the string is 2, the number of states that the DFA consists of for the given language is: 2+1 = 3 states.Here, q0 − On input 0 it goes to state q1 and on input 1 it goes to itself.q1 − On input 0 it goes to itself and on input 1 it goes to State q2.q2 − ...
Read MoreWhat is a simple assertion in C language?
An assertion is a statement which is used to declare positively that a fact must be true when that line of code is reached.Assertions are useful for obtaining the expected conditions which are met.Simple AssertionSimple assertion can be implemented by using assert (expression) method, which is present in assert.h header file.The syntax for simple assertion is as follows −assert(expression)In simple assertion, When the condition passed to an assertion which is a true, then, there is no action.The behaviour on false statements depends completely on compiler flags.When assertions are enabled, a false input causes a program to halt.When assertions are disabled, ...
Read MoreC program to perform union operation on two arrays
A union is a special data type available in C programming language that allows to store different data types in the same memory location. Unions provide an efficient way of using the same memory location for multiple-purpose.Union operationIf array 1 = { 1,2,3,4,6} Array 2 = {1,2,5,6,7}Then, union of array1 and array 2 isArray1 U array 2 = {1,2,3,4,6} U {1,2,5,6,7} = {1,2,3,4,5,6,7}Set of all elements without repetition is called union.The logic for union is as follows −for(i=0;i
Read MoreC program to perform intersection operation on two arrays
Intersection operationIf array 1 = { 1,2,3,4,6} Array 2 = {1,2,5,6,7}Then, intersection of array1 and array 2 isArray1 ^ array 2 = {1,2,3,4,6} ^ {1,2,5,6,7} = {1,2,6}Set of common elements is called an intersection.The logic for intersection is as follows −k=0; for(i=0;i
