scanf format warning for double

Question

I\'m having a small problem with a program I\'m working on, I keep getting the warning format \'%1f\' expects type \'float *\' but argument 2 has type \'double *\'

Answer 1

Use correct format specifiers for their respective data types

• float %f
• double %lf
• int %d or %i
• unsigned int %u
• char %c
• char * %s
• long int %ld
• long long int %lld
