Enter two numbers at console during runtime. Then, declare the flag variable which is used to check whether the number is prime or not with the help of for loop condition.Whenever, the flag is zero, it prints the prime number and if flag is one, it exists from the loop.ProgramFollowing is the C program to display the prime numbers in between two intervals − Live Demo#include int main(){ int number1, number2, i, j, flag; printf("enter the two intervals:"); scanf("%d %d", &number1, &number2); printf("prime no’s present in between %d and %d:", number1, number2); for(i=number1+1;iRead More
The sum of first and last digit for a number can be calculated if we use the below mentioned algorithm in C programming language.AlgorithmRefer an algorithm given herewith −START Step 1: Declare no, sum variables of type int Step 2: Read a number at runtime Step 3: Compute sum=no%10 Step 4: While loop no>9 No=no/10 Step 5: Compute sum=sum+no; Step 6: Print sum STOPExampleFollowing is the C program to find the sum of first and last digit for a number − Live Demo#include int main(){ unsigned int no, sum; printf("enter any number:"); scanf("%u", &no); sum=no%10; ...

C program is defined by set of protocols that are to be followed by a programmer, while writing the code.SectionsThe complete program is divided into different sections, which are as follows −Documentation Section − Here, we can give commands about program like author name, creation or modified date. The information written in between/* */ or // is called as comment line. These lines are not considered by the compiler while executing.Link section − In this section, header files that are required to execute the program are included.Definition section − Here, variables are defined and initialised.Global declaration section − In this ...

If we are generating random numbers in a program, it is necessary to control the series of numbers.The randomize() and srand() functions are used to seed the random number generator.The process of assigning the random number generators starting number is called seeding the generators.The randomize() uses PC’s clock to produce a random seed.srand() allows us to specify the random number generator’s starting value.ProgramGiven below is the C program on rand − Live Demo#include int main(){ // create same sequence of // random numbers on every time the program runs for(int i = 0; i
Memcmp() and memicmp() compares first n bytes of two blocks of memory.memcmp() performs comparison as unsigned characters.memicmp() performs comparison as characters but, ignore upper case or lower case letters.Both functions return an integer value.Two memory buffers are equal (returns 0).First buffer is greater than second (returns >0).First buffer is less than second(returns0) printf("buffer st1 is bigger than buffer st2"); if(x
An array of characters (or) collection of characters is called a string.DeclarationRefer the declaration given below −char stringname [size];For example − char a[50]; string of length 50 characters.InitializationThe initialization is as follows −Using single character constant −char a[10] = { ‘H’, ‘e’, ‘l’, ‘l’, ‘o’ ,‘\0’}Using string constants −char a[10] = "Hello":;AccessingThere is a control string “%s” used for accessing the string, till it encounters ‘\0’.The logic used to count number of vowels is as follows −if(string[i]=='a'||string[i]=='e'||string[i]=='i'|| string[i]=='o'||string[i]=='u')//checking the char is vowel vowel=vowel+1;The logic used to count number of digits is as follows −if(string[i]=='0'||string[i]=='1'||string[i]=='2'|| string[i]=='3'||string[i]=='4'||string[i]=='5'|| string[i]=='6'||string[i]=='7'||string[i]=='8'||string[i]=='9') digit=digit+1;The logic used to ...

Let’s take the input of 3x3 matrix, means total 9 elements, in 2D array using keyboard at runtime.With the help of it and for loops, we can display only lower triangle in 3X3 matrix.The logic to print lower triangle elements is as follows −for(i=0;i=2nd index printf("%d",array[i][j]); else printf(" "); //display blank in non lower triangle places } printf(""); }ProgramFollowing is the C program to display only the lower triangle elements in a 3x3 2D array − Live Demo#include int main(){ int array[3][3],i,j; printf("enter 9 numbers:"); for(i=0;i
An array is a group of related data items that are stored with single name.For example, int student[30];Here, student is an array name which holds 30 collection of data items, with a single variable name.OperationsThe operations of an array are explained below −Searching − It is used to find whether a particular element is present or not.Sorting − Helps in arranging the elements in an array either in ascending or descending order.Traversing − Processing every element in an array, sequentially.Inserting − Helps in inserting the elements in an array.Deleting − Helps in deleting an element in an array.In this program, ...

Perfect number is the number; whose sum of factors is equal to 2*number.AlgorithmAn algorithm is explained below −START Step 1: declare int variables and initialized result=0. Step 2: read number at runtime. Step 3: for loop i=1;i
An array is a homogeneous sequential collection of data items over a single variable name.For example, int student[30];Here, student is an array name holds 30 collection of data item, with a single variable name.CharacteristicsThe characteristics of arrays are as follows −An array is always stored in consecutive memory location.It can store multiple value of similar type, which can be referred with single name.The pointer points to the first location of memory block, which is allocated to the array name.An array can either be an integer, character, or float data type that can be initialised only during the declaration.The particular element ...
