Answer:
The hiding of the information/data in the images ,videos and audio is referred as stenography This can reduced by taking several steps like:-
- Extraction method is the widely used method for the separation and picking out the data and the image or other data forms from each other.
- Hue and saturation method works on the images and audios that can find the hidden data.
- Image processing is doen on the image which enhances the form of it by extraction of the unnecessary data from it.
Answer:
#include <stdio.h>
int main(void) {
char triangleChar;
int triangleHeight;
printf("Enter a character:\n");
scanf(" %c", &triangleChar);
printf("Enter triangle height:\n");
scanf("%d", &triangleHeight);
printf("\n");
int i, j;
for(i = 0; i < triangleHeight; ++i) {
for(j = 0; j <= i; ++j) {
printf("%c ", triangleChar);
}
printf("\n");
}
return 0;
}
Explanation:
- Get the character and height as an input from user.
- Run the outer loop up to the height of triangle.
- Run the inner loop up to the value of i variable and then display the character inside this loop.
A database? I'm not entirely sure, but i think it is called a database.
If it is a government website with the .gov url it is more reliable.
