Explanation: The standard library for input\/output is included.
Iteration is denoted by i, and user input by n. initialized to one for the factorial.
The user is asked to provide a number, which we then read.
Each time we multiply the factorial by i in a loop from 1 to n.
The computed factorial is printed following the loop.<\/p>\n\n\n
\n#include <stdio.h>\n\nint main() {\n int n, i;\n unsigned long long factorial = 1; \/\/ Use a larger type to handle big results.\n printf("Enter a number: ");\n scanf("%d", &n);\n\n for (i = 1; i <= n; i++) {\n factorial *= i; \/\/ Multiply the current factorial by i.\n }\n\n printf("Factorial of %d is: %llu\\n", n, factorial); \/\/ Print the result.\n return 0;\n}\n\n<\/pre><\/div>
