Answer:
Explanation:
A lower triangular matrix is one whose elements above the main diagonal are zero meanwhile all the main diagonals elements and below are nonzero elements. This is one of the two existing types of triangular matrixes. Attached you will find a image referring more about triangular matrixes.
If there is any question, just let me know.
Answer:
See explanation
Explanation:
//Include the
//required header files.
#include <stdio.h>
//Define the
//main() function.
int main(void) {
//Declare the
//required variables.
char input_char;
int input_int;
double input_double;
char input_string[100];
//Prompt the user
//to enter an integer.
printf("Enter integer: ");
//Read and store
//the integer.
scanf("%d", &input_int);
//Prompt the user
//to enter a double value.
printf("Enter double: ");
//Read and store
//the double value.
scanf("%lf", &input_double);
//Prompt the user
//to enter a character.
printf("Enter character: ");
//Read and store
//the character.
scanf(" %c", &input_char);
//Prompt user to
//enter the string
printf("Enter string: ");
//Read and
//store the string.
scanf("%s", input_string);
//(1)
//Display the values.
printf("%d %lf %c %s\n",
input_int, input_double,
input_char, input_string);
//(2)
//Display the values
//in reverse order.
printf("%s %c %lf %d\n",
input_string, input_char,
input_double, input_int);
//(3)
//Cast the double to
//an integer and display it.
printf("%lf cast to an integer is %d",
input_double, (int)(input_double));
//Return from the
//main() function.
return 0;
