for( index = 0; index < 10; index++ ) { if( numbers[ index ] > 50) printf("%.2lf ", numbers[ index ]); } }

double gbp_to_usd( double );
double gbp_to_usd(double);
int main(void) { double usd = 0.0;
scanf("%lf", &usd ); printf("%.2lf usd is equivalent to %.2lf gbp", usd, gbp_to_usd( usd )); }
Write a C program that asks for 5 input text strings and displays to output the largest string length value. [5 Marks]
#include <string.h>
int main(void) { char text[256] = {'\0'}; int max_length = 0; int counter;
for( counter = 0; counter < 5; counter++ ) {
scanf("%s", text ); if( strlen( text ) > max_length )
max_length = strlen( text ); }
printf("The largest string length is %d", max_length ); }
QUESTION 4

#include <string.h>
int main(void) { char text[256] = {'\0'}; int index;
