• scanf("controlstring",arg1,arg2,arg3,….,argn);
• scanf("control string", variable list);
• scanf(" varible list,", control string);
• scanf("arg1,arg2,arg3,….,argn", control string);

#include <stdio.h> int main() { int i = 10, j = 2; printf("%d\n", printf("%d %d ", i, j)); }

• Compile time error

• 10 2 2
• 10 2 5

#include <stdio.h> int main() { int i = 10, j = 3; printf("%d %d %d", i, j); }

• Compile time error
• 10 3
• 10 3 some garbage value
• Undefined behaviour

#include <stdio.h> int main() { int i = 10, j = 3, k = 3; printf("%d %d ", i, j, k); }

• Compile time error
• 10 3 3
