Created page with " == Get parameters == * interactive approach: <source lang="cpp"> #include "stdio.h" int main() { char * c; int i = 0; double d = 0.0; printf("Enter a word\n"); s..."

New page

== Get parameters ==

* interactive approach:
<source lang="cpp">
#include "stdio.h"

int main()
{
char * c;
int i = 0;
double d = 0.0;

printf("Enter a word\n");
scanf("%s",c);
printf("Enter an integer\n");
scanf("%d",&i);
printf("Enter a double\n");
scanf("%lf",&d);
printf("You gave : %s %d %lf",c,i,d);
printf("\n");

return 0;
}
</source>

* from the command line:
<source lang="cpp">
#include "stdio.h"

int main(int argc, char* argv[])
{
if(argc != 4)
{
printf("\tUsage:\t");
printf("%s",argv[0]);
printf(" <char> <integer> <double>\n");
}
else
{
char * c = argv[1];
int i = atoi(argv[2]);
double d = atof(argv[3]);
printf("You gave : %s %d %lf",c,i,d);
printf("\n");
