There are 21 people in a room. They have to form groups of 3
people each. How many combinations are possible? Write a C
program to print the same.
Answer / jagadeesh
#include<stdio.h>
long int fact(long int n);
void main()
{
long int p;
p=fact(21)/(fact(18)*fact(3));
printf("%ld",p);
}
long int fact(long int n)
{
if(n==0||n==1)
return 1;
else
return n*fact(n-1);
}

main() { printf("%d", out); } int out=100;
#include<stdio.h> int main() { int a=3,post,pre; post= a++ * a++ * a++; a=3; pre= ++a * ++a * ++a; printf("post=%d pre=%d",post,pre); return 0; }
main() { char *cptr,c; void *vptr,v; c=10; v=0; cptr=&c; vptr=&v; printf("%c%v",c,v); }
main() { static char names[5][20]={"pascal","ada","cobol","fortran","perl"}; int i; char *t; t=names[3]; names[3]=names[4]; names[4]=t; for (i=0;i<=4;i++) printf("%s",names[i]); }
void main() { char ch; for(ch=0;ch<=127;ch++) printf(ā%c %d \nā, ch, ch); }
