Below is a source code to return a maximum among five numbers. Write the source code, save it as "func6.c", and confirm whether it can run properly.
#include <stdio.h> int max_return(int a, int b, int c, int d, int e) { int max; max = a; if(max < b) max = b; if(max < c) max = c; if(max < d) max = d; if(max < e) max = e; return (max); } int main(void) { int d0, d1, d2, d3, d4; int max; printf("Input 5 integers\n"); scanf("%d %d %d %d %d", &d0, &d1, &d2, &d3, &d4); max = max_return(d0, d1, d2, d3, d4); printf("Maximum = %d\n", max); return (0); }
(Execution result) $ $ ./a.out Input 5 integers 2 8 3 6 5 Maximum = 8 $
In similarity to func6.c, below is a source code to determine a maximum among five integers. Write the source code, complement the expression hidden by "******" and save it as "func7.c". Confirm whether it can run properly.
#include <stdio.h> void max_return(int a, int b, int c, int d, int e, int *max) { *max = a; if(*max < b) *max = b; if(*max < c) *max = c; if(*max < d) *max = d; if(*max < e) *max = e; } int main(void) { int d0, d1, d2, d3, d4; int max; printf("Input 5 integers\n"); scanf("%d %d %d %d %d", &d0, &d1, &d2, &d3, &d4); ********************************************** printf("Maximum = %d\n", max); return (0); }
In similarity to func7.c, below is a source code to determine a maximum among five integers. In this programming, five integers are input into array. Write the source code, complement the expression hidden by "******" and save it as "func8.c". Confirm whether it can run properly.
#include <stdio.h> void max_return(int a, int b, int c, int d, int e, int *max) { *max = a; if(*max < b) *max = b; if(*max < c) *max = c; if(*max < d) *max = d; if(*max < e) *max = e; } int main(void) { int d[10]; int max, i; printf("Input 5 integers\n"); for(i=0; i<5; i++) scanf("%d", &d[i]); ********************************************** printf("Maximum = %d\n", max); return (0); }
In similarity to func8.c, below is a source code to determine a maximum among five integers. In this programming, address of array into which five integers are input is used in a function, "max_return". Write the source code, complement the expression hidden by "******" and save it as "func9.c". Confirm whether it can run properly.
#include <stdio.h> void max_return(int a[], int *max) { int i; *max = a[0]; for(i=1; i<5; i++) if(*max < a[i]) *max = a[i]; } int main(void) { int d[10]; int max, i; printf("Input 5 integers\n"); for(i=0; i<5; i++) scanf("%d", &d[i]); ********************************************** printf("Maximum = %d\n", max); return (0); }
In similarity to func9.c, below is a source code to determine a maximum among five integers. In this programming, pointer is used in a function, "max_return". Write the source code, complement the expression hidden by "******" and save it as "func10.c". Confirm whether it can run properly.
#include <stdio.h> void max_return(int *a, int *max) { int i; (1)********************************************** for(i=1; i<5; i++){ if(*max < *a) *max = *a; (2) ****************************************** } } int main(void) { int d[10]; int max, i; printf("Input 5 integers\n"); for(i=0; i<5; i++) scanf("%d", &d[i]); (3)********************************************** printf("Maximum = %d\n", max); return (0); }
Using any source code among func6.c to func10.c, program to show maximum and minimum among five intergers, save it as "func11.c", confirm whether it can run properly.
(Execution result) $ $ ./a.out Input 5 integers 2 8 3 6 5 Maximum = 8 Minimum = 2 $
Based on Exercise 11, program to show maximum and minimum among arbitrary number of intergers, save it as "func12.c", confirm whether it can run properly.
(Execution result) $ $ ./a.out Input integers repeatedly Exit by Ctrl-d 8 9 -3 21 -31 -2 18 <- Ctrl-d Maximum = 21 Minimum = -31 $
