C Program using structure for time format Define structure data type called time_struct containing three member’s integer hour, integer minute and integer second. Develop a program that would assign values to the individual number and display the time in the following format: 16: 40:51 In this program we are going to implement a structure called time_struct containing three member’s integer hour, integer minute and integer second.  Program: #include <stdio.h> struct time_struct {     int hour ;     int minute ;     int second ; } t ; int main ( void ) {     printf ( " \n Enter Hour : " );     scanf ( " %d " ,& t . hour );     printf ( " \n Enter Minute: " );     scanf ( " %d " ,& t . minute );     printf ( " \n Enter Second : " );     scanf ( " %d " ,& t . second );     printf ( " \n Time %d : %d : %d " , t . hour % 24 , t . minute % 60 , t . second % 60 )...

Initialization of global and static variables in C Write a C program using global variable, static variable . In C language both the global and static variables must be initialized with constant values. This is because the values of these variables must be known before the execution starts. An error will be generated if the constant values are not provided for global and static variables. A program that demonstrates the initialization of global and static variables is given as follows.  Program: #include <stdio.h> int a = 5 ; static int b = 10 ; int main () {     printf ( "The value of global variable a : %d " , a );     printf ( " \n The value of global static variable b : %d " , b );     return 0 ; }  Output: The value of global variable a : 5 The value of global static variable b : 10  Explain: The global variable a has the value 5 and the static variable b has the value 10. So, this program works as required. Visit YouTube C...

Define a structure type struct personal that would contain person name, date of joining and salary using this structure to read this information of 5 people and print the same on screen C Program to read and print employee details In this program we are going to implement a structure Personal which contains name, date of joining and salary of employees.  Program: #include <stdio.h> struct person {     char name [ 20 ];     char doj [ 10 ];     float salary ; } p [ 5 ]; int main ( void ) {     int i = 0 ;     for ( i = 0 ; i < 5 ; i ++)    {       printf ( " \n Enter person name :" );       scanf ( " %s " , p [ i ]. name );       printf ( " \n Person Date of joining(dd-mm-yyyy) : " );       scanf ( " %s " , p [ i ]. doj );       printf ( " \n Enter person salary : " );       scanf ( " %f " ,& p [ i ]. salary ); ...
